Experimental direct-sequence spread-spectrum digital mobile radio transmission
2006This paper is concerned with the conception and the realization of a direct-sequence spread-spectrum digital mobile radio transmission at 910 MHz. The system has been used either as a spread-spectrum communication modem or as a wideband channel sounder.

Direct Sequence Spread Spectrum (DSSS) Baseband Transmitter
2016As today’s mixed signal chips often require both digital and analog system components on the same substrate, an interesting area of application for silicon nanowire technology is to build a Direct Sequence Spread Spectrum (DSSS) baseband transmitter.

Concurrent bus based on direct sequence spread spectrum
2008 International Conference on Information and Automation, 2008Many industrial control site use field bus such as RS485, RS232 or CAN or some other bus. However, data terminals can not transmit information simultaneously or initiatively through these bus. The paper presented a new technology of industrial field concurrent bus communication. It based on direct sequence spread spectrum, used frequency division multi

Compressive sensing of direct sequence spread spectrum signals
SPIE Proceedings, 2014In this paper, Compressive Sensing (CS) methods for Direct Sequence Spread Spectrum (DSSS) signals are introduced. DSSS signals are formed by modulating the original signal by a Pseudo-Noise sequence. This modulation spreads the spectra over a large bandwidth and makes interception of DSSS signals challenging.

Novel direct sequence spread spectrum multiple access technique
MILCOM 2000 Proceedings. 21st Century Military Communications. Architectures and Technologies for Information Superiority (Cat. No.00CH37155), 2002Code reuse multiple access (CRMA) is a new communication technique (patent pending) that employs direct sequence spread spectrum signaling for the access channel. It is similar to the spread ALOHA CDMA (SA/CDMA) and spread ALOHA multiple access (SAMA) multiple access techniques.

Novel low cost direct sequence spread spectrum synchroniser
Proceedings of 1996 Canadian Conference on Electrical and Computer Engineering, 2002Spread spectrum systems have become more and more popular, with many commercial systems appearing on the market. One of the more complicated areas of spread spectrum systems is code acquisition and tracking. Many acquisition and tracking methods have been presented in the literature. These various methods differ in complexity, performance and cost.

Acquisition of Direct-Sequence Spread-Spectrum Signals
1997In order to successfully demodulate a digitally modulated signal, the receiver must first synchronize its oscillators and clocks to the received signal. If direct-sequence spread-spectrum modulation is used, then it is also necessary to synchronize to the code sequence that was used to produce the spectral spreading.

Basic Properties of Direct Sequence Spread Spectrum Signals
2020In order to utilize the frequent sign altering in the spreading codes to measure the distance accurately, and to achieve better performance of multiple access, multipath resistance, and anti-interference, direct sequence spread spectrum (DSSS) technology is used in satellite navigation signals.
