ABSTRACT:
Subscriber power levels are adjusted to enhance interference cancellation in a DS-CDMA communication system. A base-station of the communication system receives signals from a plurality of subscribers and evaluates each signal. Based on the evaluation, particular subscribers are commanded to control their power levels such that different predetermined targets for the particular subscribers are maintained. The predetermined targets include, but are not limited to, received power, frame erasure rate, bit error rate and signal quality. The resulting power levels received at the base-station are substantially different, which is beneficially employed to enhance interference cancellation in the DS-CDMA communication system.
