Abstract
A system and method for providing a configurable signal processing circuit for a field configurable radio frequency communication system that is adaptable to be configured to function with a variety of signaling schemes or waveforms, and including an intermediate frequency (IF) digital signal processing circuit. A “tool box” of configurable signal processing circuits is available for processing multi-bit digital signals into and out of the IF circuit. Control registers receive digital instructions to select, interconnect and configure various circuits from the tool box to provide added signal processing for the selected the transmitter or receiver mode of operation as a function of the selected signaling scheme.
