Abstract :
A constrained optimized multiuser detector for asynchronous CDMA Channel is presented. It is shown that the solution of the proposed detector is equal to the decorrelating detector with more simple implementation, while no channel estimation is necessary except for the synchronization of the desired user. Simulation results demonstrate that the proposed detector achieves good performance when the multipath length is short.
