Biography Khoirul Anwar Inventor 4G

                           One more Indonesian researchers who have incised achievements in the international arena. He is Prof. Dr. Khoirul Anwar, inventor and owner of 4D technology-based patent of OFDM (Orthogonal Frequency Division Multiplexing). His findings were then awarded Best Paper for Young Scientist category at the 2010-Spring Institute of Electrical and Electronics Engineers Vehicular Technology Conference (IEEE VTC) held 16-19 May 2010, in Taiwan. Now the patented findings are being used by a large Japanese electronics company. Lecturer and researcher working in the laboratory Information Theory and Signal Processing, Japan Advanced Institute of Science and Technology, in Japan is a graduate of the Department of Electrical Engineering, Bandung Institute of Technology with cum laude predicate in 2000. He then won a master's degree from Nara Institute of Science and Technology (NAIST) in 2005 and a doctorate in 2008 on the same campus. In 2006, he also received the IEEE Best Student Paper Award of IEEE Radio and Wireless Symposium (RWS), in California. Khoirul also received an award in the field of Foreign Scientific Contribution by the Indonesian Consulate General Osaka in 2007.

                      Son of the couple (deceased) Sudjianto with Siti Patmi, never forget the origin. The result of his first patent royalty he gave to his mother who now lives farming in Kediri. Khoirul Anwar was born on 22 August 1978 in Kediri, East Java. His father died of illness when he graduated elementary school in 1990. Ibunyalah then try hard to send him to school. To complete his S1, he managed to get a scholarship for 4 years in a row. In fact he managed to get a S2 scholarship from Panasonic, and scholarship S3 from Japanese companies. Together with his wife, Sri Yayu Indriyani and his three beloved sons, Khoirul lives in Nomi, Ishikawa, not far from his workplace. Despite the brilliant achievement in Japan, but Khoirul save the desire to return to Indonesia someday.

The invention of 4G

                    Big INSPIRATION can indeed come from anywhere, including from animated movies for kids. You probably never thought, an Japanese anime movie could inspire an important discovery that revolutionized the unbreakable assumption in the wireless telecommunication transmission universe. But the story is what happened to Khoirul Anwar, a lecturer and researcher from Indonesia who works in the laboratory Information Theory and Signal Processing, Japan Advanced Institute of Science and Technology, in Japan.

When pressed for proposing a research theme to raise research funding, Khoirul racked his brain. Finally the idea came from Dragon Ball Z, Japanese animation film that he often watch. When Goku, the main character of Dragon Ball Z, wants to cast his most famous stance, 'Genki Dama' aka Spirit Ball, Goku will absorb all the energy of living beings in nature, resulting in tremendous power.

"The concept that I put down the mathematical formula to apply to my research," said Khoirul, to VIVAnews via electronic mail, Friday, August 13, 2010.
So the inspiration now manifests into a paper titled "A Simple Turbo Equalization for Single Carrier Block Transmission Without Guard Interval."

                       Khoirul gives the Spirit Ball Goku a Turbo Equalizer (decoder turbo) capable of collecting all the energy from a delayed transmission block, as well as an earlier transmission block, to eliminate data distortion due to wave interference. The 31-year-old Assistant Professor can break the notion that was initially 'impossible' in the telecommunications world. Now a signal transmitted wirelessly, no longer need to be guarded by a guard interval (GI) to keep it immune to delay, reflection, and interference. Turbo equalizer will cancel the interference so that the receiver can receive the signal without distortion. Removing the GI, and utilizing the turbo decoder, can theoretically eliminate the loss of transmission power because it does not need to transmit power to GI. The loss of GI can also be filled by parity bits that can be used to correct errors due to distortion (error correction coding).

"GI is actually something 'useless' on the receiver other than just to be a barrier. So sending power to something 'useless' is useless, "Khoirul said.

This idea itself, done Khoirul with Tadashi Matsumoto, professor in the laboratory where Khoirul work. At that time he and Tadashi were about to propose a project to Kinki Mobile Wireless Center.After deducting his mathematical formula concretely, Khoirul asked his colleague Hui Zhou, to create his program. This method can be considered to solve the problem of wireless transmission. Moreover, it can be applied to almost all telecommunication systems, including GSM (2G), CDMA (3G), and is suitable to be applied to 4G systems that require high performance with a low level of complexity.

It can also be applied Indonesia, especially in large cities that have many skyscrapers, as well as in the mountains. Because in the area was usually transmitted wave to reflect and delay longer.
It is no wonder that these findings cast the Best Paper award for the Young Scientist category at the 2010-Spring Institute of Electrical and Electronics Engineers Vehicular Technology Conference (IEEE VTC) held 16-19 May 2010 in Taiwan.
Now the patented findings are being used by a large Japanese electronics company. Even this technology is also being explored by China's telecom giant, Huawei Technology.

Early Education Khoirul Anwar

                          This was not Khoirul's first success. In 2006, the man from Kediri, East Java has also found ways to reduce transmission power in multicarrier systems such as Orthogonal frequency-division multiplexing (OFDM) and Multi-carrier code division multiple access (MC-CDMA). The trick is to introduce spreading code using Fast Fourier Transform so the complexity becomes very low. With this method it can reduce power fluctuations. Then the telecommunication equipment used does not need to provide backup for high power. Later, these findings he patented. This technique has been used by Japanese satellite companies. And that also made him startled, 4G system was very similar to the findings that he patented it.

                However, the son of the couple (deceased) Sudjianto with Siti Patmi, never forget the origin. The result of his first patent royalty he gave to his mother who now lives farming in Kediri. "This is as a form of my appreciation to parents, especially Mother," he said. Khoirul's father died of illness, when he graduated from elementary school in 1990. Ibunyalah then tried hard to send him to school, although his parents no one graduated from elementary school.

Since childhood, Khoirul lived in poverty. But there is a way for him to continue to study. Suppose, when continuing high school in Kediri, suddenly there are people who offer free boarding for him. As he continued his studies at ITB Bandung, for 4 years he always get a scholarship. "My parents do not have to send any more money," Khoirul recalls his past. Her moncer's brain continues to bring Khoirul into high education.

                He got a S2 scholarship from Panasonic, and then a S3 scholarship from a Japanese company. "Alhamdulillah, though I am not from a rich family, can still go to school until S3. I sincerely thank all the scholarship givers, "he said.

Khoirul Anwar Not forgetting Indonesia

                        Success in the land of the people does not make him forget the land of birth. "One time I will also return to Indonesia. Having gained a lot of knowledge abroad, "said Khoirul. Beyond his life as a researcher, Khoirul also teaches and guides his master's and doctoral students. The depth of religious knowledge of men who had become takmir mosque in his high school, also took him often to give religious lectures in Japan, even became Khatib prayer Iedul Fitri. Not only that, Khoirul also often invited to give a lecture of Indonesian culture. "Our existence abroad does not mean we do not love Indonesia, but instead we as ambassadors of Indonesia," he said.

During the teaching of Indonesian culture, he heard many comments about his homeland. Some praise Indonesia, of course, some are blasphemous. For the latter, he usually answers in Japanese: Indonesia ha mada ganbatteimasu (Indonesia is trying and struggling).

The Khoirul Anwar family

                     Now, Khoirul lives in Nomi, Ishikawa, not far from his workplace, with his wife, Sri Yayu Indriyani, and his three beloved sons. "All of my children have met the arithmetic series of formula 1.5 years," Khoirul explained. The biggest one was born in Kawasaki, Yokohama, 7 years old. The second was born in Nara aged 5.5 years, and the third was also born in Nara, now 4 years old. He disagreed with some of his Japanese colleagues, who said the family presence would interfere with his research. For him many families provide inspiration in finding new ideas. "Lately I have found a new and highly efficient technique for wireless network when playing with children," he said.

                             Instead, Khoirul often invites his children to conduct small-scale research in his home. Together with his children, Khoirul often spend time watching together, especially his favorite animated films: Dragon Ball Z, Kungfu Panda, Gibli, or Detective Conan.

"Animated films teach our children the value we need to understand in life," Khoirul said. Gibli animated film, for example, tells a lot how humans should be friends with nature, do not destroy it, and love living beings.

                             Even new ideas and passions sometimes come from watching movies. For example the value of life he learned from the movie Kungfu Panda: 'There is no secret ingredient, just believe'. "This value I mean that there is no secret of success, believe that anything we do can make us successful," said Khoirul.
