Performance evaluation of channel coding for Gbps 60-GHz OFDM-based wireless communications

Abstract

In this paper, we undertake a comparison of LDPC (768,384) and convolutional (171,133) codes for 60-GHz OFDM-based wireless communication systems. The comparison is based on two parameters: Frame Error Rate (FER) for 60-GHz channels and decoding hardware complexity for a required throughput of more than 1 Gbps. Additionally, we provide performance parameters of a fully parallel LDPC decoder chip, fabricated in our IHP in-house 0.13 μm CMOS technology, achieving a throughput of more than 1 Gbps.
