CDMA, Blind, Decision Directed, Interference Suppression


Rapid and effective suppression of multiuser interference in direct-sequence code-division multiple-access (DS-CDMA) communication systems is demonstrated for a 255 chip system with 139 active users. In particular, we use the low complexity, partial-bit DS-CDMA receiver to suppress interference, with out requiring knowledge of interfering users spreading codes, timing or phase information. Training signals, during startup, are not required as well.
