Experimental Approach of the Quality of Analog Receivers in an Overlay Spread Spectrum Scenario
This paper presents results of a laboratory test held to examine the conditions under which analog PAL-G and analog FM signals can share spectrum with Spread Spectrum systems. RF protection ratios and SNR Degradation for both PAL-G television and FM radio systems are derived in the case of co-channel spread spectrum interference. Results for different Spread Spectrum RF bandwidths and carrier f...
متن کاملEfficient Spectrum Sharing in the Presence of Multiple Narrowband Interference
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...
متن کاملPerformance Analysis of DS Spread Spectrum System in Multiple Narrowband Interference
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 mul...

The investigation of spectrum overlay of a Spread Spectrum system on the existing narrowband FM broadcasting system1 is presented. The overlaid Spread Spectrum (SS) system is assumed to utilize direct sequence (DS) spreading, using maximal length pseudorandom sequences. We studied the performance degradation of the analog FM system due to the interference produced by the SS signal, through labo...
متن کاملEvaluation of TV and radio performance in the coexistence of a spread spectrum system
Abstract – Performance degradation of an analog FM and PAL-G signal due to Spread Spectrum (SS) interference is investigated. An analytical expression between RF TV protection ratio (CIR) and baseband unweighted Signal-toNoise ratio (SNRV), for co-channel spread spectrum and noise interference, is derived. Also, we expressed the audio frequency signal-to-noise ratio (AF SNR) output due to SS ov...
