Abstract

The Turbo receiver for MIMO channels employs a soft-input, soft-output (SISO) detector followed by a SISO channel decoder. In this letter, we describe and analyze two low complexity SISO detectors named as M-Partial-MAP and L-Partial-MAP for LDPC coded MIMO systems. The latter performs slightly better than the former at the price of some computational complexities.
