Abstract

In this paper we present the mutual information of a bit-interleaved V-BLAST space-time architecture. We assume interference cancellation by successive detection using MMSE equalizers without decoding of the channel codes. The mutual information is dependent on the MIMO channel realization and the detection order. However, the mutual information is very similar to that of an AWGN channel when plotted over the SINR per stream. The mutual information can be used for developing adaptive modulation and coding methods for V-BLAST.
