Performance Analysis of DS Spread Spectrum System in Multiple Narrowband Interference
نویسنده
چکیده
The investigation of spectrum overlay of a Spread Spectrum system on the existing narrowband FM broadcasting system is presented. The Spread Spectrum (SS) system is assumed to utilize direct sequence (DS) spreading, using maximal length pseudorandom sequences with long spreading codes. We studied the performance analysis of the SS system due to the overlaying analog FM system, consisting of multiple narrowband FM stations. The SS signal is evaluated for various types of spreading scenarios, for different carrier frequency differences ∆f and for various signal-to-interference ratios. Key-Words: Spread Spectrum, Direct Sequence (DS), Analog FM, AWGN, Interference, Bit-Error-Rate.

Interpolation Lattice Filters for Narrowband Interference Cancellation in PN Spread Spectrum Communication Systems
Previous work on the adaptive lattice filters for narrowband interference rejection in a direct sequence (DS) spread spectrum communication system has centered around the use of one-sided prediction only. For two-sided interpolation, that is known to achieve better interference rejection than its one-sided counterpart, only the least-mean-squared (LMS) algorithms have been considered thus far i...

In this paper, we study the spectrum usage efficiency by applying wideband methods and systems to the existing analog systems and applications. The essential motivation of this work is to define the prospective coexistence between analog FM and digital Spread Spectrum systems in an efficient way sharing the same frequency band. The potential overlaid Spread Spectrum (SS) system can spectrally c...

The technology of Direct Sequence Code Division Multiple Access (DS-CDMA) has been chosen for mobile communication systems because of numerous advantages. A major advantage is that it can provide a better capacity compared to the other possible technologies of multiple access [1]. In a spread spectrum system, the signal bandwidth is increased to a value much larger than is needed to transmit th...
متن کاملPerformance Comparison of Spread Spectrum Methods in an Hf Interference Environment
Since the interfering signals from other users of the spectrum is a main problem in HF communication, it is necessary to consider them when evaluating HF radio systems. Based on the Laycock-Gott congestion model, a statistical HF interference model is derived and brieey compared to real measurements. The two basic methods to apply spread-spectrum modulation in radio communication are frequency-...
