Abstract

ajuste de otimização de pa para esquemas de modulação com largura de banda variável. a presente invenção refere-se a um método para aprimorar o consumo de energia de uma cadeia de transmissão pela variação do ponto de operação de um amplificador de energia para otimizar (por exemplo, reduzir) a corrente que é consumida pelo amplificador. o ponto de operação é variado pela alteração da(s) tensão(ões) de ajuste (por exemplo, tensão de alimentação, tensão inativa) do amplificador para um valor predeterminado que é escolhido com base no efeito que uma dada característic a de esquema de modulação do sinal transmitido (por exemplo, largura de banda de canal e/ou número de subportadoras) tem no ponto de operação de um amplificador de energia. por exemplo, se as características indicam um desempenho amplificador de energia bom, a capacidade de energia de saída linear de um amplificador de energia pode ser rebaixada, pela alteração da(s) tensão(ões) de ajuste alimentada(s) ao amplificador de energia para reduzir a capacidade de energia de saída e o consumo de corrente do amplificador de energia.
