60-GHz single-carrier coherent detection system with robust 16-QAM signal recovery
Wireless Communications and Networking Conference（2014）
Abstract
This paper describes a millimeter wave wireless system using the 60-GHz frequency band, focusing on the data recovery algorithm and implementation to compensate for both the phase noise and the DC offset. Our robust baseband system supports data transfers at 7.04 Gbps using 16-QAM single-carrier with effective digital compensation, an improved adaptive equalizer, and a post-phase rotator and post-shifter. We use a low-overhead frame format without training symbols in the payload and RS(255, 239) as the error correction code so that we can retain spectral efficiency with an effective data rate around 6.6 Gbps with a bit error rate of 4.0E-5 at 3 m distance. Our results show how millimeter wave technology can provide higher data rates and higher aggregated channel capacities for future dense networks.
