Successive Interference Cancellation for Distributed Space-Time Coding in Cooperative Cellular Systems

A signal detection technique using successive interference cancellation (SIC) for uplink cooperative cellular systems is proposed in this paper, to suppress the interference caused by the cooperative transmission of two mobile users transmitting both their own information and the cooperative partner's information using distributed space-time coding (DSTC). Simulation results show that the proposed scheme outperforms the existing joint DSTC and equalization scheme in terms of system performance with time division multiple access.
