Abstract
The present invention is a method and system for processing communication signals in a wireless telecommunication system having at least two subscriber units. The subscriber units communicate with each other through a selected band of radio frequencies over a plurality of radio frequency channels. The system generates a fixed based radio frequency signal and a digital intermediate frequency signal. The fixed based radio frequency signal and the digital intermediate frequency signal are then combined to produce a carrier signal which is communicated between the at least two subscribers.
