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 6Gb/s and use rate adaptive low-density parity-check (LDPC) codes as the main form of forward error correction. State-of-the-art flexible LDPC decoders cannot simultaneously achieve the high throughput mandated by these standards and the low power...
The wide unlicensed bandwidth of a 60 GHz channel presents an attractive opportunity for high data rate and low power personal area networks (PANs). The use of single-carrier modulation is beneficial for efficient transmitter and receiver implementation. Equalization of the long channel response in non-line-of-sight (NLOS) conditions presents a significant challenge. A digital equalizer for 60 GHz...
A parallel low-density parity-check (LDPC) decoder is designed for the (2048,1723) Reed-Solomon-based LDPC (RS-LDPC) code suitable for 10GBASE-T Ethernet. A two-step decoding scheme lowers the error floor to a 10−14 BER. The decoder architecture is optimized for area, power, and high throughput. The resulting 5.35 mm2, 65nm CMOS chip achieves a decoding throughput of 47.7 Gb/s. With scaled frequency...
