Abstract

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

高频谱效率MIMO通信系统非线性软输出信号检测器的设计与实现

非线性MIMO信号检测器的VLSI实现并不简单，特别是对于具有高频谱效率的系统。例如，使用64-QAM实现4 × 4 MIMO的这种检测器在公开文献中仍然缺失。为了应对这一挑战，我们开发了一种非线性软输出检测器设计方案，在此基础上，使用0.13mum CMOS技术设计了具有64-QAM的高达4倍4 MIMO的检测器。基于布局后的结果验证了75 Mbps以上的检测吞吐量
