Abstract—In this paper, VLSI implementation of a configurable,
soft-output MIMO detector is presented. The proposed chip can
support up to 8
8 64-QAM spatial multiplexing MIMO commu-
nications, which surpasses all reported MIMO detector ICs in an-
tenna number and modulation order. Moreover , this chip provides
configurable antenna number from 2

8 and modula-
tion order from QPSK to 64-QAM. Its outputs include bit-wise log
likelihood ratios (LLRs) and a candid
