Performance Evaluation of Low Density Parity Check Codes for IEEE 802.11n and Its ASIC Design

In this paper we investigate the performance enhancement due to the implementation of low density parity check (LDPC) codes on IEEE 802.11n system under channel model B TGn and its application specific integrated circuit design. Simulation result shows that LDPC codes gives 6 dB better performance compared to binary convolutional codes. Logic synthesis on 0.13 mum CMOS technology with low-power standard cell library shows that the proposed min-sum algorithm-based LDPC decoder is suitable for portable devices.
