Transmission power level estimation
Abstract
A transmission power level of a selected user is estimated in a code division multiple access (CDMA) communication system. An initial estimate of a transmit power level associated with the selected user is determined. A transmit power level of users of the system other than the selected user is provided. Subsequent estimates for the selected user and the other users are estimated using previous transmit power level estimates of the selected user and the other users. The estimating subsequent estimates is repeated with a last repetition's estimated transmit power levels for the selected and other users being the estimated transmit power levels of the selected and other users.
