ABSTRACT:
A high PN code rate receiving system is provided for receiving, recovering and tracking a high rate PN composite code comprising a low rate PN code combined with a high rate PN code and wherein the receiving system comprises a broad band receiver for receiving the high rate PN composite code and further includes a data recovery channel and a tracking loop channel. The data recovery channel comprises a high rate mixer and a low rate mixer for removing the high data rate component code and the low data rate component code to provide a low data rate data stream. The tracking loop channel comprises a high rate early-late tracking system for producing a high rate error signal and further comprises a low rate portion of the tracking loop for producing a low rate error signal which is combined with the data output to provide a clock error signal. The clock error signal is applied to a voltage controlled oscillator to produce a low data rate clock and a high data rate clock which are coupled to a low data rate code generator and a high data rate code generator which synchronize the tracking loop and said data channel.
