Design of Reconfigurable Carrier NCO and PN Code NCO in Satellite Navigation Receiver

The compatible receiver for satellite navigation is the trend of the receiver along with appears a variety of satellite navigation system. The basic structure of carrier NCO and PN code NCO was designed according to the parameters which are determined on the basis of the introduced theory of reconfigurable carrier NCO and PN code NCO. The hardware testing of the designed carrier NCO and PN code NCO had finished in the end, and the result shows that the carrier NCO of and PN code in accordance with the design parameters; therefore ,the design can process dissimilar navigating signal, which is used in the channel processing of reconfigurable navigating signal directly. It is a firm base of researching and exploiting compatible receiver for a variety of satellite navigation system in the future.
