| Abstract(in English) | In this paper, a novel highly spectral efficient wireless communication system is investigated, which transmits multiple co-channel signals from multiple transmit antennas at the same time. In this system, the bit-error-rate performance severely degrades in line-of-sight propagations such as Nakagami-Rice fading channels and quasi-static channels. A technique using trellis-coded modulation can improve this degradation, that is known as trellis-coded co-channel interference canceller or trellis-coded space-time transmission. The receiver employs maximum likelihood sequence estimation extended to multi-signal detection. This technique shows excellent performance over multi path propagations or line-of-sight propagations. However, it offers almost no advantage in non-line-of-sight propagations. This paper proposes a spatial interleaving technique for acquiring a coding gain over flat fading channels, and shows performance improvements of trellis-coded space-time transmission system with this technique. |
