Abstract
A first signal generator is arranged to generate a first signal. A compensating null code circuit is configured to provide a null code. A multiplexer is capable of multiplexing the first signal and the null code consistent with a predetermined time sequence for expression of the null code in a produced precursor signal. A ranging code generator is arranged for generating a ranging code. A mixer is capable of accepting the ranging code and the precursor signal and outputting a locally generated reference signal. After down-conversion and digitization of the received composite signal, the code correlator can correlate the digital received composite signal to the locally generated reference signal to decode at least a first portion of the received composite signal, while leaving a second portion of the received composite signal undecoded.
