Group-wise successive interference cancellation in multirate CDMA systems
Paper in proceeding, 1999

In this paper, the performance of variable processing gains (VPG) and multicode (MC) systems employing a group-wise successive interference canceller (GSIC) is analysed. The GSIC is an interference canceller performing group-wise signal estimation using matched filters and successive cancellation between the groups. The results for long random codes show that the systems converge to similar performance. Before convergence, the two schemes have however different performance. For the first few stages the MC scheme performs better than the VPG scheme, while the VPG scheme obtains the lowest minimum BER.
