Recently, the cooperative communication has been proposed and studied to improve the system performance in wireless communication environments. In this paper, we propose the STBC (Space Time Block Coding) cooperative communication system with interference cancellation scheme. The multiple cooperated relay nodes that help the source signal forward are considered to be the multiple transmit antennas. The STBC scheme is applied to achieve higher diversity gain without the transmitter knowing the CSI (Channel State Information) and to decrease the complexity of the transceiver. However, if errors occur at relay nodes because of the frequency selective fading channel, error propagation would lead to degradation of the system performance when the decoded signal is retransmitted to the destination. To solve this problem, interference canceller is employed at the relay nodes when we decoded the source signals in the proposed system. Simulation result shows that better performance is achievable when interference canceller and STBC schemes are used in the PB/MC-CDMA (Partial Block Multi-Carrier CDMA) system.
