This paper analyzes the benefit of power control and multiuser linear detection for CDMA uplink transmissions. Several papers have recently shown a benefit for such an approach in the case of synchronous uplink transmissions without multipath propagation. We study the impact of a multipath channel on the system level performance. ZF and MMSE multiuser block linear receivers are considered for various scenarios to compare them and to analyze the influence of multipath propagation and of out-cell interference. The results are compared to the performance obtained with a RAKE receiver.
