A gradient method is used to obtain the signal constellation that yields to the minimum error probability over a channel affected by non-linear amplification and additive noise. The results show the dominance of Phase Shift Keying when the amplifier is driven near saturation, and the better performance given by Amplitude-Phase Shift Keying if the amplifier is operated in its linear region.

Abstract
A gradient method is used to obtain the signal constellation that yields to the minimum error probability over a channel affected by non-linear amplification and additive noise. The results show the dominance of Phase Shift Keying when the amplifier is driven near saturation, and the better performance given by Amplitude-Phase Shift Keying if the amplifier is operated in its linear region.File in questo prodotto:
