Abstract
Disclosed is a frequency mapping system (10) including a data processor (12) and a control word memory (16) to be used with a pseudo-random (PN) number generator (32) and a frequency synthesizer (34). The processor receives an input that specifies those frequencies in a frequency band that are available for communications, associates each specified frequency with a respective control word that designates a carrier frequency to the frequency synthesizer, and stores the control words corresponding to the specified frequencies in the control word memory. Once the control word memory is mapped, the PN generator produces code words that address locations in the control word memory whereby the control words in the addressed locations are sent to the frequency synthesizer.
