Spread Spectrum technique is a digital passband technique. It uses a special code which is known only to the transmitter and receiver of that message. The special code appears as a noise signal to the jammer who tries to jam the channel. In this paper, we present the Direct Sequence Spread Spectrum. Firstly, we show an overview of Direct Sequence Spread Spectrum, then, we simulate Direct Sequen...

This paper compares the performance of phased chirp spread spectrum and direct sequence spread spectrum technique for multiple access over different fading channels. The direct sequence spread spectrum technique is motivated by the inherent interference rejection capability of such spread-spectrum type system, especially in circumstances where immunity against Doppler shift and fading due to mu...

—In this paper, we will review spread spectrum signaling techniques in terms of performance, applications and implementation. Specifically, we focus on direct sequence spread spectrum signaling and CDMA, as the most important applications of spread spectrum signaling techniques, analyzing them in details. With a number of theoretical derivations and simulations, their mathematical characterist...
