Abstract

We study a multirate layered architecture for multiple-input multiple-output (MIMO) quasi-static Rayleigh fading channels, which uses a diagonal space-time interleaved (DSTI) coded modulation and a low complexity linear successive decoding receiver. The key challenge involved with this architecture is estimating the per-layer rates. We derive the probability density functions of per-layer mutual information, which are used to estimate the per-layer rates that maximize the information rate subject to an upper bound on the outage probability. Based on these rates, we design punctured turbo codes and the simulation results show significant gains in bit error rate (BER) performances. In comparison with the BLAST architecture, the proposed multirate system has more practical virtues while achieving near capacity performance for sufficiently large diversity orders.
