Abstract:
1. A receiver for receiving a received composite signal, the receiver comprising: a receiver front-end for down-converting a received composite signal; an analog-to-digital converter for converting the received composite signal to a digital received composite signal; a first signal generator for generating a first signal; a ranging code generator for generating a ranging code; a mixer accepting the ranging code and the first signal and outputting a locally generated reference signal; a code correlator for correlating the digital received composite signal to the locally generated reference signal to decode at least a first portion on the received composite signal, while leaving a second portion of the received composite signal undecoded; and a tracking loop signal processor for processing the locally generated reference signal with respect to the digital received composite signal to maximize correlation of the received composite signal to the locally generated reference signal wherein the received composite signal comprises a multiplexed binary offset carrier (MBOC) signal, where a first portion of the received composite signal comprises a first binary offset carrier (BOC) (n,m) signal component, where a second portion of the received composite signal comprises a second binary offset carrier (BOC) (o,p) signal component, where n, m, o and p are integer values, and where the locally generated reference signal is associated with the first BOC (n,m) signal component that is temporally dominant in a majority of the time slots of the MBOC signal.
