Abstract
A method, system, and computer program product for controlling amplification of an input transmit signal in a transmitter in order to operate a digital-to-analog converter such that its clipping point corresponds to a desired cumulative distribution level. The input transmit signal is coupled to a digital-to-analog converter and includes a plurality of independent spread spectrum channels. The spread spectrum channels have associated individual channel gains. The invention includes an approximating the total variance of the input transmit signal and determining an amplification gain corresponding to the desired cumulative distribution level using an amplification function dependent on the total variance of the input transmit signal.
