Abstract

"PROCESSO E APARELHO PARA CONTROLAR A POTêNCIA DE TRANSMISSãO EM UM SISTEMA DE RáDIO COM SALTOS DE FREQuêNCIA" Potência de transmissão que em um sistema de rádio com saltos de freq³ência que transmite pacotes de uma unidade de rádio remetente para uma unidade de rádio receptora, em que cada pacote inclui um endereço designando a unidade de rádio receptora, é controlada por medição de intensidade de sinal recebido de pacotes cujos endereços foram recebidos com sucesso na unidade de rádio receptora, independente de se outras porções dos respectivos pacotes foram recebidas com sucesso. Um valor médio de intensidade de sinal é gerado das medições de intensidade de sinal recebido. A diferença matemática entre o valor médio de intensidade de sinal e um valor alvo associado com a unidade de rádio receptora é, então, determinada e usada como uma base para decidir se enviar uma mensagem de controle de potência da unidade de rádio receptora para a unidade de rádio remetente. A fim de proporcionar uma histerese no processo de controle de potência, uma mensagem de controle de potência é enviada da unidade de rádio receptora para a unidade de rádio remetente, se a diferença matemática for maior do que um primeiro limite de decisão ou se a diferença matemática for menor do que um segundo limite de decisão. A mensagem de controle de potência pode incluir a diferença matemática que, quando recebida pela unidade de rádio remetente, é usada como uma base para determinar uma quantidade de ajuste de nível de potência de transmissão. O valor alvo, contra o qual o valor médio de intensidade de sinal é comparado, pode estar baseado na sensibilidade do receptor ajustada para levar em conta as perdas de implementação e outras imprecisões.
