Abstract

AJUSTE DE TRANSMISSOR COM BASE NA CONFIGURAçãO DO SINAL EM DISPOSITIVOS DE COMUNICAçãO SEM FIO. Um método em um transmissor de comunicação sem fio que inclui um processador de banda base (310) que configura dinamicamente o transmissor para uma configuração de sinal particular, e uma controladora de espaço de folga (350) para ajustar o espaço de folga do transmissor com base na configuração de sinal particular. Em uma versão, o espaço de folga PA é controlado com base em uma métrica de energia, por exemplo, uma métrica de polinomial de terceira ordem ou de proporção pico a média (PAR), que é uma função da configuração do sinal. Em outra versão, o espaço de folga PA é ajustado utilizando informação em uma tabela de pesquisa.
