Influence of the Amplitude Limitation of Signals with the sin(x)/x Envelope on the Spectral and Energy Characteristics

Abstract

Nonlinear distortions of spectrally efficient signals conditioned by using TWT amplifier are investigated. Influence of AM-AM and AM-PM conversions on signals with the sin/x envelope with different duration are considered. Signal oscillograms, spectrums and BER performance are obtained at the input and output TWT amplifier.
