VLSI implementations of nonlinear MIMO signal detectors are not trivial, particularly for systems with high spectral efficiency. For example, realization of such a detector for 4 times 4 MIMO with 64-QAM still remains missing in open literature. To tackle this challenge, we developed a nonlinear soft-output detector design solution, based on which a detector for up to 4 times 4 MIMO with 64-QAM has been designed using 0.13mum CMOS technology. Above 75 Mbps detection throughput has been verified based on post-layout results
