Abstract

We consider the design optimization of the irregular repeat accumulate (IRA) codes for multiple-input-multiple-output (MIMO) systems employing iterative receivers. We present the density evolution-based procedure for optimizing IRA code ensemble with the extrinsic information transfer (EXIT) chart matched with that of the soft MIMO demodulator. With a code ensemble mapping relationship between an IRA code and an LDPC code, an optimal IRA code can also be obtained by transforming an optimal LDPC code designed for MIMO systems. Two types of soft MIMO detectors are treated, namely, the MAP detector and the soft interference canceller with linear MMSE filtering (SIC-MMSE).
