Turbo-Blast

TURBO-BLAST is a novel multi-transmit multi-receive (MTMR) antenna scheme for high-throughput wireless communications. It exploits the following ideas: (1) The Bell-Labs Layered Space Time (BLAST) architecture. (2) A novel space-time coding scheme by using the independent block codes and space-time interleaving that are designed off-line. (3) Sub-optimal turbo-like receiver that per­forms joint decoding of the proposed space-time codes in an iter­ative and, most important, simple fashion.The net result is a new transceiver that is not only computationally efficient but it also yields a probability of error performance that is orders of magnitude smaller than traditional BLAST schemes for the same operating conditions. In this paper, we also describe simulation results on fading channels, which confirm these findings.
