    Abstract
    Disclosed are apparatus that implement blind selected mapping techniques that provide for crest factor reduction of forward link CDMA signals. Communication signals are processed using a mathematical algorithm that selectively maps a summed communication signal in a frame to another summed communication signal which has a smaller peak-to-average power ratio. The reduced dynamic range communication signal is amplified and transmitted to a receiver. At the receiver, the reduced power communication signal is processed using a mathematical algorithm that detects the selected mapping index used in the transmitter and converts the received signals into the original communication signals.
