Linear diversity precoding design criterion for finite block-fading parallel MIMO channels

Popis výsledku v původním jazyce

A novel optimal two stage coding for finite set of parallel flat-fading MIMO channels with single common information source with specific constant rate requirement is derived. The optimality of suggested coding is achieved in terms of the capacity versusoutage performance. The well-known optimal coding rule relies on Gaussian codewords spanned over the whole available finite set of parallel channels. We prove that the equivalent preprocessing to the ideal interleaving is to re-code independent parallelchannels codewords by a linear inner precoder from a special class of unitary precoders complying with the optimality criterion derived in the paper. Performing such linear mixture of codewords sharing common Gaussian block-wise codebook, the same capacity versus the outage is guaranteed without any interleaving over parallel channels.We utilize a virtual multiple access (VMA) channel approach to derive the optimality criterion.
