Abstract

"AJUSTE DE GANHO AUTOMáTICO EM UM SISTEMA DE COMUNICAçõES CELULAR". Um método para ajustar um nível de potência em uma rede de comunicações que inclui uma primeira pluralidade de elementos de transmissão de sinal adaptada para receber sinais acoplados a uma segunda pluralidade de elementos de transmissão de sinal adaptada para transmitir os sinais, o método incluindo a desativação de pelo menos alguns dentre a primeira pluralidade de forma que os sinais não sejam recebidos na primeira pluralidade e desativação de pelo menos alguns dentre a segunda pluralidade de forma que os sinais não sejam transmitidos da segunda pluralidade. O método inclui injetar um sinal de referência possuindo um nível de potência injetada predeterminado na primeira pluralidade, receber o sinal de referência na segunda pluralidade, medir um nível de potência recebida do sinal de referência na segunda pluralidade, comparar os níveis de potência injetada e recebida, e, em resposta à comparação, ajustar um ganho de pelo menos um dentre os elementos de transmissão de sinal compreendidos nas primeira e segunda pluralidades.
