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 wide-band signals of multiple transmit antennas. The performance of the proposed scheme was investigated using Quadrature-Phase-Shift-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.
