Method of processing a direct sequence spread spectrum communication system signal wherein digital data comprised of data bits is modulated by a first pseudo-noise code comprised of a sequence of chips, the pseudo- noise chip rate greater than said date bit rate, each chip having a chip period...
A practical DSSS communication system based on TMS320c5416 Digital Signal Processor is designed in the paper, which consists of baseband modulator, IF modulator/demodulator, local oscillator, antenna, Liquid crystal displays monitor and TMS320c5416 DSP, etc. The experiment result of transmission shows...
The abbreviationDSSSstands forDirect Sequence Spread Spectrum, a modulation technique used in telecommunications that spreads a signal over a wider bandwidth to improve resistance to interference and jamming. It is commonly employed in wireless communication technologies, particularly in CDMA (Code Division...

Apparatus for indicating the end of an acquisition procedure between a transmitter and receiver in a direct sequence spread spectrum communications system. A transmitter generates a first acquisition code having a first acquisition code period and comprised of digital bits at a first bit rate. A circ...
1.0 Direct Sequence Spread Spectrum (DSSS) Modem Reference Design Functional Specification 14 Introduction Much of the signal processing performed in modern wireless communications systems—such as digital modulator/demodulator applications—takes place in the digital domain and requires high throughput. ...
In this paper, we consider broadband jammer suppression in direct sequence spread spectrum (DSSS) communication systems. The transmitted signal in DSSS systems occupies a bandwidth much wider than the bandwidth necessary to send the information. Hence these systems are inherently immune to outside inte...
