A Power-Efficient Soft-Output Detector for Spatial-Multiplexing MIMO Communications

A Power-Efficient Soft-Output Detector for Spatial-Multiplexing MIMO Communications

VLSI implementation of a configurable power-efficient MIMO detector is proposed to support 4×4 spatial multiplexing and modulation from QPSK to 64-QAM. A novel tree search algorithm is proposed to enable the detector to provide soft outputs and to be implemented in parallel and pipelined hardware ar...
