Abstract: An apparatus and method of reducing a peak envelope power of a linear power amplifier (10) amplifying a plurality of channels is provided. The method includes the steps of measuring (104) the peak envelope power of the linear power amplifier, measuring a channel activity level (101) of each channel of the plurality of channels, and, when the peak envelope power exceeds a first threshold, changing (103, 106) at least one parameter of a channel of the plurality of channels having a channel activity level exceeding a second threshold to reduce the peak envelope power.

Abstract: In a wireless communication system, a chip time is selected in a complex pseudonoise (PN) sequence generator. For a next chip time following the selected chip time, a phase difference between a previous complex PN chip and a next complex PN chip is restricted to a preselected phase angle. In one embodiment, every other chip time is selected and the preselected angle is 90 degrees.
