Code-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 کاملJoint Blind Multipath Diversity Combining and PN Code Timing Recovery for Direct-Sequence Spread-Spectrum Systems
A RAKE receiver accomplishing joint blind multipath diversity combining and PN code timing recovery is proposed for direct-sequence spread-spectrum signaling over a frequency-selective fading channel. In this technique, an improved known modulus adaptive algorithm is exploited to perform multipath diversity combining in the blind mode, while a modified PN code timing recovery technique based on...
متن کاملOn cracking direct-sequence spread-spectrum systems
Secure transmission of information over hostile wireless environments is desired by both military and civilian parties. Direct-sequence spread spectrum (DS-SS) is such a covert technique resistant to interference, interception and multipath fading. Identifying spread-spectrum signals or cracking DS-SS systems by an unintended receiver (or eavesdropper) without a priori knowledge is a challengin...
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 کاملVariable dwell-time code acquisition for direct-sequence spread-spectrum systems on time-variant Rayleigh fading channels
Variable dwell-time code acquisition based on multiple-dwell or sequential linear tests is investigated for direct-sequence spread-spectrum systems on time-variant Rayleigh fading channels. Not like in the conventional additive white Gaussian noise channels, the channel memory incurred by fading renders the exact analysis of the acquisition systems extremely difficult, if not impossible. In thi...
