ABSTRACT:
An apparatus and method thereof for processing base band signals to reduce peak power requirements for a multi-channel transmitter is disclosed. The apparatus includes a first Fourier Transform Matrix (FTM) coupled to one or more input signals for providing a plurality of output signals; a processing unit for limiting a peak value for each of the output signals, and a second FTM for decomposing the peak limited output signals to provide one or more output base band signals, each of the output base band signals corresponding to one of the input signals. A multi-channel transmitter further converts the output base band signals to a radio frequency signals; a first analog FTM provides a plurality of amplifier input signals; a power amplifier having a plurality of amplifiers provides a plurality of amplified output signals; and a second analog FTM coupled to the amplified output signals provides transmit signals corresponding one to one with the output base band signals.
