    We analyze the performance of truncated power control in a code division multiple access communication system. This power control scheme compensates for fading above a certain cutoff fade depth: below the cutoff level an outage is declared. We investigate the power gain of this power control scheme relative to conventional power control as a function of outage probability. It is found that truncated power control is most effective for channels with large power fluctuations or large background noise. We then apply truncated power control to multimedia systems, where different traffic types have different performance requirements (e.g. outage probability, bit error rate, information rate, etc.) For these systems truncated power control can significantly reduce the required transmit power for each traffic type.
