- Abstract
- This paper presents an area/energy efficient soft-output
MIMO detector that supports the detection of spatial-multiplexing
(SM), spatial-diversity (SD), and space-division-multiple-access (SDMA)signals. The developed near-optimal detection algorithms for these tree modes share most of the mathematical operations to enable extensive
hardware reuse. A unified VLSI architecture is accordingly designed to
be reconfigured to different modes. The detector was implemented using
a 65-nm CMOS technology with 0.25 mm2 core area, representing a
70% hardware-resource saving to state-of-the-art detectors. Operating
at 167-MHz clock frequency with 1.2-V supply, the detector achieves... (More) - This paper presents an area/energy efficient soft-output
