The optimum selection method and performance analysis for Weil code of satellite navigation system

With the development of GNSS, the design and optimum selection of the ranging code is of significant importance for navigation system design. This paper describes the generation of the Weil code based on the design of ranging code. And then in order to select ranging codes of better performance, the paper describes a new optimum selection method in detail. This method is a combination of code selection method which is based on MFL and performance analysis method which is based on the peaks of correlation. And the performance of the selected Weil codes is analyzed by the methods based on peaks of correlation and Welch bound. The results demonstrate that the optimum selection method is of good rationality and of great importance for the design of navigation signals.
