The coordination of power control and soft handover has a major effect on DS-CDMA systems. In this paper, we investigate the power controlled DS-CDMA reverse-link performance under soft handover with convolutional coding scheme. It is shown that system under soft handover has less sensitivity against incrementing the number of users. The effect of the link balance is evaluated through simulation by considering the reverse-link behavior with power control and soft handover. It observed that the differential loss between two links under soft handover decreases the uplink performance. Finally it is pointed out that by using convolutional error correction coding scheme an additional gain is obtained.
