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.

First claim

The following is claimed:

1. A receiver for receiving a composite signal, the receiver comprising:
a receiver front-end for down-converting a composite received signal;
an analog-to-digital converter for converting the composite received signal to a digital composite received signal;
a first signal generator for generating a first signal;
a compensating null code circuit for generating a null code or null logic level that compensates for any offset or float in the first sign…
