Emerging standards for wireless communications in the 60GHz band, such as WiGig, IEEE 802.11ad, and IEEE 802.15.3c, require throughputs between 1.5 and 6 Gb/s and use rate adaptive Nonbinary Low Density Parity Check (NB-LDPC) codes as the main form of forward error correction. State-of-the art flexible NB-LDPC decoders cannot simultaneously achieve the high throughput mandated by these standards and...
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,...
