INTERFERENCE CANCELLATION FOR NON-ORTHOGONAL CHANNEL SETS

摘要

Techniques for interference cancellation in a CDMA system. In an exemplary embodiment, a channel set scrambled using a secondary scrambling code (SSC) is estimated and cancelled along with a channel set scrambled using a primary scrambling code (SSC). The estimation and cancellation of the SSC channel set may proceed in series with the estimation and cancellation of the PSC channel set. Alternatively, the estimation of the SSC channel set may proceed in parallel with the estimation of the PSC channel set, and the cancellations of the PSC and SSC channel sets may be simultaneously performed. Multiple iterations of such estimation and cancellation may be performed in a successive interference cancellation (SIC) scheme.
