Multistep closed-loop power control using linear receivers for DS-CDMA systems.

Multistep closed-loop power control using linear receivers for DS-CDMA systems.

A closed-loop power control strategy, which includes both power control and power allocation functions, for a code-division multiple-access system is proposed. The target power level for a minimum mean squared error (MMSE) or a matched filter (MF) linear receiver is iteratively computed, and the pow...
