Single-Carrier Space-Time Trellis and Space-Time Block Coding for Dispersive Rayleigh Fading Channels

In this contribution we propose a novel Space-Time Coding (STC) scheme for transmissions over dispersive Rayleigh fading channels, which invokes a Joint-Detection assisted Minimum Mean Square Error based Decision Feedback Equalizer (JD-MMSE-DFE) for jointly detecting the channel-impaired wideband signals of multiple transmit antennas. The performance of the proposed scheme was investigated using Quadrature-PhaseShift-Keying (QPSK) when communicating over channels exhibiting multi-path components. It was shown that the scheme advocated outperforms conventional STC due to benefitting from the multi-path diversity of the dispersive channel.
