Abstract :
A turbo frequency domain equalisation (T-FDE) scheme for space-frequency block-coded (SFBC) single-carrier systems is proposed. The received signal is space-frequency decoded first, then the T-FDE is performed, which exchanges extrinsic information between the minimum mean square error (MMSE)-based frequency domain equaliser (FDE) and the decoder according to the turbo principle. The simulation results demonstrate that better performance can be achieved using the proposed scheme compared with non-iterative detection.
