Adaptive blind multiuser detection in asynchronous CDMA

This paper applies blind source separation (BSS) to the design of an adaptive blind multiuser detector for an asynchronous code division multiple access (CDMA) system. Our starting hypotheses are the spreading factor and the number of users transmitting in the system. We assume too that we do not have knowledge of the spreading sequences or the delays affecting each of the users in the system. The proposed blind receptor has a similar performance compared to the synchronized matched filter.
