Abstract

<B>SISTEMA E MéTODO PARA A PRODUçãO DE SINAL AMPLIFICADO OU VERSõES DELE<D> Um sistema de amplificação de sinal envolve transformar pelo menos um sinal a ser amplificado em pelo menos um sinal transformado o qual é amplificado e o (s) sinal (is) transformado (s) amplificado (s) resultante (s) pode (m) ser utilizado (s) para produzir uma (s) versão (ões) de pelo menos um sinal original. Pelo menos um sinal transformado pode ser produzido de pelo menos um sinal original utilizando pelo menos um sinal original para modular em amplitude e/ou ângulo (fase ou freq³ência) pelo menos um sinal original. Após amplificação de pelo menos um sinal transformado, pelo menos um sinal transformado amplificado resultante é desmodulado para produzir uma (s) versão (ões) de pelo menos um sinal. Ao transformar pelo menos um sinal original para produzir pelo menos um sinal transformado, pelo menos um sinal original é transformado em uma forma mais desejável, como uma forma mais eficiente em termos de potência, para amplificação. Pela amplificação de pelo menos um sinal transformado, amplificador (es) mais eficiente (s) e/ou mais barato (s) pode (m) ser utilizados para amplificar pelo menos um sinal em um modo linear. Dependendo da modalidade, pelo menos um sinal a ser amplificado pode ser transformado pelo menos em um sinal transformado pela combinação de versões descentradas de pelo menos um sinal original para produzir pelo menos um sinal transformado tendo uma razão (ões) de pico reduzido para potência média (PAR). Múltiplos sinais a serem amplificados podem ser transformados em pelo menos um sinal transformado pela combinação dos múltiplos sinais, por exemplo para produzir pelo menos um sinal transformado tendo uma (s) razão (ões) de pico reduzido para potência média (PARs). Após pelo menos um sinal transformado ser amplificado, o (s) sinal (is) resultante (s) podem ser desmodulados, inversamente transformados, unidos ou reconstruídos para recuperar uma (s) versão (ões) do (s) sinal (is) original (is).
