Abstract

This article the formation of S/A - Code detail its ACF and CCF, in comparison with the max length sequence  and Gold-sequence. Shows the ambiguity function and its sections at different levels. Also calculated the potential resolutions for the S/A - package. The article shows the formation of C/A - Code (C/A - coarse/acquisition, or clear/ acquisition), which used for Global Positioning System. Detaily investigated by the autocorrelation and crosscorrelation function of the code, in comparison with the max length sequence and Gold’s sequence. Ambiguity function and its sections at different levels were calculated in the strong and weak correlation, and the potential resolutions for the given code was calculate. In this paper, we calculated the amplitude and phase spectrum of the signal and its bandwidth.
