Abstract
Spread spectrum facilitated the using of communication channels. Also it has improved signal privacy against noise jammers and interference. Althogh the privacy of spread spectrum technique is robust against signal jammers and interference with respect to its processing gain , but it can further be improved by side-lobe suppression an and decreasing of side-lobe integration in spread spectrum systems that use match filter for synchronization and despreading of SS receivers .This paper will illustrate a new technique to improve the decrement of side-lobe in comparison with other common related methods such as amplitude weighting.
