Interference and noise suppressions using spread spectrum systems

Reviews strategies of suppressing interference and noise under various circumstances in order to justify the applications of spread spectrum systems. The basic principles of spread spectrum systems are discussed to demonstrate their capabilities of suppressing noise and interference, and other significant advantages of using such systems. The paper is also examines the factors which affect the capability for interference and noise suppressions and the performance of the systems. It is obvious that the systems can suppress various forms of interference and noise effectively and still achieve other significant goals. The ability of suppressing noise and interference depends on the process gain and correlation properties of the codes of the systems. The overall system performance depends on the degree of synchronization which can be accomplished by the systems.
