Abstract :
This paper presents a new linear blind adaptive multiuser detector in multipath fading asynchronous DS/CDMA system. With a taped delay line scheme, multipath diversity and adaptive multiuser co-channel interference (CCI) suppression can be realized at the same time. The object cost function is properly constrained in order to obviate training. Simulations have proved it has a better performance compared with the linear blind adaptive receiver and the conventional RAKE receiver
