Patent ID: 6985704

Claim:
A system for signal processing in preparation for wireless transmission, the wireless transmission being from a portable wireless communication device, wherein the wireless transmission includes use of a power amplifier having nonlinear characteristics, the system comprising: memory for storing digitally-indexed information, wherein the digitally-indexed information models nonlinear characteristics of the power amplifier, and the digitally-indexed information is stored prior to processing of a first signal that reflects information to be communicated; first logic, configured to accept the first signal and to retrieve, based on the first signal, a portion of the digitally-indexed information stored in the memory; second logic, configured to generate a second signal based on the portion of the digitally-accessed information and on the first signal, wherein the second signal pre-compensates for the nonlinear characteristics of the power amplifier, and the second signal is for wireless transmission of a signal based on the second signal.
