Abstract :
Bandwidth efficient turbo codes have demonstrated good performance in single-antenna links. This paper is motivated by the need for applying such approaches to multiple-antenna links, and fulfilling relatively low-complexity decoding method in a turbo space-time coded modulation system. Our scheme evolved from symbol-interleaved turbo trellis coded modulation, then to make an iterative decoding procedure fit in multiple-antenna links, the zero-forcing algorithm and an antenna selector are introduced in a 2-transmitter system.
