摘要
Spread spectrum (SS) technique can be considered as one of the most important secure communication techniques. It consists of many types such as direct sequence (DS), frequency hopping (FH), time hopping (TH), and hybrid spread spectrum (HSS). Most of the recent researches focused on the DS/FH hybrid spread spectrum, however a little researches discussed the DS/FH/TH hybrid spread spectrum. This paper presents and evaluates the performance of a new secured coded DS/FFH/TH multi-user hybrid spread spectrum system under Rayleigh flat fading channel. The performance evaluated using four different types of spreading codes with different lengths, and different number of multiple access interferences. The results show that the system provides a superior performance under flat fading conditions in presence of high multiple access interference especially with the chaotic codes.
