This paper investigates into the performance of sampling rate on time discrimination of PRN code in GNSS, proposes an innovative performance evaluation criterion for actual time discrimination of noncommensurate sampling technique, and then develops an algorithm to quickly obtain this criterion. Computer simulation verification guarantees the correctness of the proposed fast algorithm. The proposed algorithm can be adopted in all PRN code ranging based applications to choose the "better" sampling rate, which could achieve better time discrimination performance with lower sampling rate. |
