Abstract

We propose a bit interleaved coded modulation with iterative decoding (BICM-ID) scheme for MIMO systems using systematic linear codes with low-density generator matrix (LDGM). We compare the performance of the proposed scheme with the (constrained input) channel capacity and show its ability to perform close to the theoretical limit. The main advantage of the proposed structure relies on its low encoding and decoding complexity.
