Performance Evaluation and ASIC Design of LDPC Decoder for IEEE802.11n

Abstract

This paper presents our investigation on performance enhancement due to the implementation of low density parity check (LDPC) codes on IEEE 802.11n system and its Application Specific Integrated Circuit design. Simulation result shows that in higher coding rate, LDPC codes gives 6 dB better performance compared to binary convolutional codes. Logic synthesis is succesfully done on 0.13 µm CMOS technology with low-power standard cell library.
