Abstract

In article consideration of correlation properties of various binary sequences which can be applied to signals with code division in system GLONASS is spent. The analysis of sizes of correlation functions lobes of these sequences is carried out both at absence, and in the presence of frequency shifts between signals. Also sizes of the lateral lobe of autocorrelation function nearest to the main maximum are considered. The choice ofparametres of Weil codes minimising this size is made. The Weil codes providing the least multipath error are found.
