摘要：
The use of a blind scheme for suppressing interference in direct-sequence code-division multiple-access (DS/CDMA) communication systems is investigated, In particular, we use a blind version of the partial-bit DS/CDMA receiver to successfully suppress narrow-band and near-far multiple-access interference without requiring knowledge of other users' spreading codes, timing or phase information. Performance results for a 23 user/100 chip BPSK DS/CDMA system indicate that the blind partial-bit DS/CDMA receiver using as little as 33 taps can suppress narrow-band and near-far multiple-access interference, either at the beginning of a transmission or during transmission as interferers gain access to the system.
