Is Prof. Dr. Khoirul Anwar, who discovered and patent owner of OFDM-based 4G technology (Orthogonal Frequency Division Multiplexing). If you ever watch the show Kick Andy , would already be familiar with the figure Khoirul Anwar.
Khoirul Anwar are alumni of Electrical Engineering ITB with cum laude in 2000, then continued his education at the Nara Institute of Science and Technology (NAIST) and obtained a master's degree in 2005 and doctorate in 2008. He is also the recipient of the IEEE Best Student Paper Award of the IEEE Radio and Wireless Symposium (RWS) in 2006, in California.
The discovery of OFDM-based 4G technology diawalinya with the "crazy idea" to reduce the transmission power to increase the speed of data transmission. Loss of power is up to 5dB alone (100,000 = 10 ^ 5 times smaller than previous technologies) and the result is the transmission speed increases.
In both patents, Khorul Anwar re-create the world in awe, this time is to remove all guard interval / GI, of course it only made a different frequency will collide, rather than picking up speed. However, indigenous children from Kediri Indonesia is compensating for this risk by developing a special algorithm in the laboratory, the result of interference can be overcome with the same performance as usual with the GI system.
