Abstract :
Several fractionally spaced equalizers (FSE) which could be used in 60GHz systems are presented in this paper. For 60GHz systems, low-power equalization algorithms are favorable. We focus on FSE in both time domain (TD) and frequency domain (FD) in order to meet different complexity requirements of 60GHz systems. Compared with symbol spaced equalizer (SSE), FSE can relax the requirement of sampling synchronization hardware significantly. Extensive simulation results show that our equalization algorithms not only eliminate ISI efficiently, but are also robust to timing synchronization errors.
