Abstract:

Space-time block coding combined with single carrier frequency domain equalization is an attractive technique to combat inter-symbol interference caused by frequency selective fading.In this paper,we firstly investigate the performance of the Alamouti code combined with single carrier frequency domain equalization,then the coding scheme and the corresponding detecting scheme in the receiver when the number of transmitting antennas are more than 2 are designed.Simulation results show that the space-time block coded single carrier frequency domain equalization system exhibits good performance,even when the maximum time delay is up to tens of symbol period.Therefore,this technique is likely to have broad prospect in high-speed wireless transmission.

Key words: space-time block code, single carrier frequency domain equalization, ,frequency selective fading channel
