Yurchuk A. Probability increase of satellite signals detection based on the modification of compression operator

The dissertation is dedicated to the relevant topic of the probability increase of satellite signals detection based on the modification of compression operator under conditions of priori uncertainty, related to multipath signal propagation. I have developed an approach of generation of non-commercial components of pseudo-casual GALILEO signal, through apply of which it is possible to generate from component in the MatLab environment any of the signal codes of GALILEO system and COMPASS satellite system. I have investigated the influence of multiple rereflection of satellite signal under urban conditions, that leads to multipath effect and deterioration of signal/noise ratio. Signal detection characteristics have been formed via computer modeling without multipath effect, and with different amount (from 1 to 4) of rereflected signals that help to evaluate bad influence of multipath effect. For the first time the modification of discrete compression operator based on polynomial approximation of primitive and sub-integral function considering analytical relations, that helps to increase signal/noise ratio while detecting satellite signals with multipath effect.
