There has been an MoU between Bandung Institute of Technology (ITB) and Japan Advanced Institute of Science and Technology (JAIST) for academic cooperation programs. One of those programs is in form of short research program. Ardimas Andi Purwita, master student at ITB, joined this short research program from November 2013 to January 2014. During this three months, he studied about the “performance and analysis of the accumulator-assisted distributed turbo codes for relay network” under the guidance of Asst. Prof. Khoirul Anwar. He belongs to the Information Theory and Signal Processing Laboratory which is well-known for its wireless communication related research.
The purpose of this short research program was to understand the relay networks, system model used as basis, decoding structure, extrinsic information transfer (EXIT) chart analysis, bit-error-rate (BER), performance in AWGN channels and frame-error-rate (FER) n frequency-flat block Rayleigh fading channels using computer simulation, and accumulator-assisted distributed turbo codes (ACC-DTC) for relay networks. To attain deep understanding, the ACC-DTT is reconstructed. The comparison was also done by verifying his own results with the results from Khoirul Anwar’s paper. In addition, to strengthen his understanding, outage analysis, power allocation, and comparison with the conventional Decode-and-Forward (DF) relay networks result were also done.
This program gave him great experience to study directly with prominent scholars in the field of wireless communication. “I hope this program will continue and benefit more students in ITB in grasping the latest wireless technology and experiencing great research environment”, said Ardimas.
