This thesis introduces a Binary CDMA technology that can transmit Multi-Code CDMA signals in a conventional Time Division Multiple Access (TDMA) structure, maintaining the characteristics and mode of Multi-Code CDMA and keeping transmission signals at a constant level. In this thesis, we consider the Code Select (CS/CDMA) and Hierarchical CDMA (HC/CDMA) only.Although the spread spectrum systems enjoy a natural immunity to interference from narrowband sources, but the channel interference or hostile jamming will influence the performance of the digital communication systems . In this thesis we consider rejection the interference used the tapped delay line-type structures and self-adapted least mean square (LMS) estimation techniques. We examined the various methods through the computer simulations for example, by increasing the spreading factor we conclude that the performance of Code Select CDMA system is close to DSSS CDMA system in the jamming environment, and the Anti-jamming algorithms is better for the tone-jamming and noise jamming rejection.
