The performance of wideband code division multiple access (WCDMA) can be severely degraded as the number of users increases due to the increase in interference. Multi-user detection is a scheme, which can cancel the interference generated by other users and hence can improve the system capacity. Recently a joint successive interference cancellation with interleaving (JSICI) scheme has been proposed for multi-user detection. However the complexity of the scheme is very high. In this paper, we propose a low complexity architecture which can implement this JSICI scheme efficiently in VLSI. Also low power features are proposed.
