Abstract

Diversas técnicas de modulação quaternárias apresentadas em publlcações recentes para aplicações a canais não Iineares são analisadas através do modelo QAM (Modulação de Amplitude em Quadratura). Para este tlpo de canal desaja-se que o sinal modulado, além de elevada eficiência na ocupação do espectro de freqüências, também apresente pouca variação de envoltória. Estas propriedades são também discutidas aqui.
