Abstract

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_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 (Δf).
