Focus on the uplink of WCDMA, in this paper, a spatial-temporal processing technology based on blind source separation (BSS) is proposed. That aims to separate the interference from the mixtures and as such produce the spread spectrum signal with reduced jammer contamination exploiting only the assumption of mutual independence between the sources, and achieves despreading at the same time. This approach can be applied to further immune system against near-far effect. This decreases the system multiple access interference (MAI), increases the system capacity. Simulation is performed to validate superiority of the approach.
