LDPC Architecture for Improved BER in Wireless Networks

Abstract

To achieve high throughput in wireless networks a partial parallel LDPC decoder is proposed in this paper. For fullyparallel decoders, it suffers from large hardware complexity caused by a large set of processing units and complex interconnections. In wireless networks coding complexity and routing congestion can be reduced by designing the decoder with partially-parallel architecture. The partially-parallel architecture with Split Row algorithm reduces the total global wire length by about 26% without any hardware overhead and increasing the throughput by 60% and 71% in wireless networks.
