Abstract

We propose interference cancellation in multiuser relay network with improved Amplify-and-Forward (AF) and Decode-and-Forward (DF) relay protocols. We use Dirty Paper Coding (DPC) and Thomilson Harashima Precoding (THP) for the Precoding schemes allied with detection techniques as Zero Forcing (ZF), Minimum Mean Square Error (MMSE) and Successive Interference Cancellation (SIC) and Ordered Successive Interference Cancellation (OSIC). Simulation Results proves that observe that the proposed schemes shows the best performance.
