Abstract
We propose TURBO-BLAST, a novel multi-transmit, multi-receive antenna scheme, for high data rate wireless communications based on the Bell-Labs Layered Space Time (BLAST) architecture. In the TURBO-BLAST (T-BLAST) scheme, the incoming substreams use the same forward error correction (FEC) code, but they are interleaved differently using randomly generated inter-substream permuters. The transmitter structure leads to an iterative ("Turbo-like") receiver for decoding the simultaneously transmitted data. For the receiver, we consider the design and performance evaluation of an iterative and parallel soft interference-cancelation scheme followed by maximum-ratio combining (MRC) since it is simple and effective.Keywords
