Signal splitting method for limiting peak power in a CDMA system
First Claim
1. A method for limiting peak transmit power in a wireless communication system, comprising:
- using a transmitter for providing a plurality of transmit waveforms, wherein each transmit waveform, of the plurality of transmit waveforms, comprises a plurality of portions;
selecting a non-fixed individual time offset for each of the plurality of transmit waveforms according to an algorithm; and
delaying transmission of each transmit waveform, of the plurality of transmit waveforms, by its corresponding non-fixed individual time offset, wherein the plurality of portions of each transmit waveform is transmitted in a sequence to limit peak transmit power.

Abstract
The invention is a method for limiting the peak transmit power in a CDMA communication system. At least one of first and second high transmit power regions are separated into a plurality of high transmit power subregions. The high transmit power subregions of the plurality of high subregions are shifted by time offsets of differing durations to provide a plurality of time offset subregions. First and second low transmit power regions are also provided. At least one of the first and second low transmit power regions is also separated into a plurality of transmit power subregions and the low transmit power subregions are shifted by time offsets of differing time durations. The subregions can be time offset by a predetermined time duration or by a random time duration.
