The Usage of Turbo Code in the Signal of Galileo System

This paper is used to simulate and realize the CDMA code -turbo code in the Galileo System. In Galileo system the signal is very complex which autocorrelation function needs very good property. How to use the code efficiency to improve the channel performance is a significant problem especially in the Galileo system. There are five parts in the paper. We show the general meaning of signal of Galileo system in the part I, part II is the general ides about Galileo frequency signals, part III is the principle of the turbo code and the BOC modulation, part IV is the simulation about turbo code in the Galileo system, and part V is the conclusion in the paper. It firstly gives the idea of turbo code which used in the signal of Galileo system. We use the complexity of the method of code to compensate for the reliability of information. The results of simulation realize the rate of 1/2, 1/3 and 1/4 spread code which efficiency is near to the theoretical values.
