Abstract

OFDM transmission has been proposed in the literature for relay nodes to combat the time delays from the relay nodes, where the paths from relay nodes to destination node are treated as multipaths and space-time (or frequency) coding is used to achieve the spatial (or multipath) diversity. With this approach, when the cyclic prefix (CP) length is lessthan the time delay length, inter-block interference occurs. In this paper, we consider Alamouti coded OFDM systems in cooperative communications where the CP length may be less than the time delay length. By taking the advantage of the Alamouti code structure, we propose a time domain interference cancellationalgorithm. Simulation results show that the performance is significantly improved with our newly proposed time domain interference cancellation algorithm.
