The Simulation of RS Codes and QC-LDPC Codes Concatenated in COFDM System
International Journal of Hybrid Information Technology, 2015In OFDM system,error correction coding is essential to ensure the effective and reliable transmission in channels of various types of data. This paper mainly focus on cascading coding of RS codes, interweaving and QC-LDPC codes,using this encoding with OFDM system to construct new COFDM system.

Efficient Decoding of QC-LDPC Codes Using GPUs
2011In this work, we propose an efficient quasi-cyclic LDPC (QCLDPC) decoder simulatorwhich runs on graphics processing units(GPUs). We optimize the data structures of the messages used in the decoding process such that both the read and write processes can be performed in a highly parallel manner by the GPUs.
