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 phase shift keying (QPSK) when communicating over channels exhibiting multipath components. It was shown that the scheme advocated outperforms conventional STC due to benefitting from the multipath diversity of the dispersive channel.
