An overlapping window decorrelating multiuser detector for DS-CDMA radio channels.

A new multiuser detector for direct-sequence code-division multiple-access communication systems is described. The proposed detector divides the received signal stream into a number of overlapping windows and decorrelates them window by window. This scheme is justified by an analysis of the converge...
