Performance analysis of CDMA2000 under the multiuser environment

A pilot aided Space-Time receiver structure that an antenna array is combined with a Rake receiver to make use of the profits of space and time processing at the cell site of Wide-band CDMA is proposed. The performance of the receiver is investigated for a single user reception under the multiuser environment and a simple simulation result is given. The result shows that the receiver can greatly improve the BER performance compared with the traditional receiver without power control.
