Evaluation of TV and radio performance in the coexistence of a spread spectrum system

Performance degradation of analog FM and PAL-G signals due to spread spectrum (SS) interference is investigated. An analytical expression between RF TV protection ratio (CIR) and baseband unweighted signal-to-noise ratio (SNR/sub V/), for cochannel spread spectrum and noise interference, is derived....

Zusammenfassung:Performance degradation of analog FM and PAL-G signals due to spread spectrum (SS) interference is investigated. An analytical expression between RF TV protection ratio (CIR) and baseband unweighted signal-to-noise ratio (SNR/sub V/), for cochannel spread spectrum and noise interference, is derived. Also, we express the audio frequency signal-to-noise ratio (AF SNR) output due to SS overlay for various types of spreading scenarios and for different carrier frequency differences (/spl Delta/f).
