Abstract
Space-time multipath (STM) coding techniques are described for frequency-selective channels, respectively. The described STM coded system guarantees full space-multipath diversity, and achieves large coding gains with high bandwidth efficiency. The techniques utilize a linearly coding technique, and incorporates subchannel grouping for application of the linear coding techniques. As a result, the techniques enable desirable tradeoffs between performance and complexity.
