Abstract

This paper studies the influence of sampling clocks on pseudo-code generating accuracy of high-precision BOC signal simulator. In the first part, A high-precision clock pseudo-code generating model of navigation signal simulation source was established. Secondly, the sampling-clocks’ impacts on pseudo-code generating accuracy of high-precision BOC signal analog source in single-bit digital quantization is analyzed, and the relationship of pseudo-code generating accuracy, sampling-clocks frequency and the phase noise is derived. Moreover, the software receiver is used to accomplish the numerical simulation process. The aim of this paper is to provide a theoretical basis on design and implementation of the high-precision BOC signal simulator.
