Detection of Direct Sequence Spread Spectrum Signals
Since early experimentation in the late 1800’s, wireless communication has become increasingly important and has been widely adopted by civilian and military markets worldwide. The proliferation of wireless communication systems presents new challenges, threats and opportunities for society and government institutions. Although the possibility of infringing privacy laws exist, electronic survei...
متن کاملCode-Time Diversity for Direct Sequence Spread Spectrum Systems
Time diversity is achieved in direct sequence spread spectrum by receiving different faded delayed copies of the transmitted symbols from different uncorrelated channel paths when the transmission signal bandwidth is greater than the coherence bandwidth of the channel. In this paper, a new time diversity scheme is proposed for spread spectrum systems. It is called code-time diversity. In this n...
متن کاملDirect Sequence Spread Spectrum with Barker Code and QPSK
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...
متن کاملPerformance of low-complexity code acquisition for direct-sequence spread spectrum systems
The authors consider a low-complexity technique for direct-sequence spread spectrum code acquisition. They present performance analysis in Rayleigh fading channels, and with carrier frequency offset in the receiver. They derive analytical expressions for acquisition probabilities, and use them to determine the mean and variance of the acquisition time. It is shown that acceptable performance ca...
متن کاملDetection of direct sequence spread spectrum transmissions without prior knowledge
Direct sequence spread spectrum transmissions (DSSS) are now widely used for secure communications, as well as for multiple access. Since the transmission uses a large bandwidth, the power spectral density of a DS-SS signal can be below the noise level. Hence, such a signal is difficult to detect. In this paper, we propose a method which is able to detect a spread spectrum signal hidden in the ...
