A Snapshot-Replay Method of Pseudo-Code Ranging under Frequency Limited Fading Channel

Abstract:

This paper focuses on the method of pseudo-code ranging based on time divided CDMA-OFDM mixed signal system. A snapshot-replay method is proposed to make the receiver provide the measurement result of pseudo-code ranging under frequency fading channel, which enhance the continuity of the output of pseudo-code ranging result. The problem of ranging through tracking loop under frequency fading channel is analyzed. This paper analyzed and studied the design and realization of snapshot-replay method of pseudo-code ranging. Further, the impact due to limited frequency band is analyzed. Through software simulation and hardware verification, this method of snapshot-replay pseudo-code ranging is proved to be effective to enhance the continuity of the output of pseudo-code ranging result.
