Abstract

"MECANISMO PARA CONTROLE DE POTêNCIA EM MúLTIPLOS ESTADOS PARA UM SISTEMA DE COMUNICAçãO SEM FIO". Um mecanismo de controle de potência possuindo vários estados e adequado para um sistema de comunicação em que as transmissões de dados não são contínuas (isto é, ocorrem em rajadas) Em uma modalidade, uma unidade de controle de potência inclui um processador de dados, uma máquina de estado e um elemento de ajuste de limite. O processador de dados recebe e processa um sinal de entrada para prover estados de frames de dados recebidos a partir do sinal de entrada para uma transmissão de dados específica. A máquina de estado recebe os estados de frames e provê um estado corrente para a unidade de controle de potência. O estado corrente é indicativo de um status de uma sessão de comunicação específica que inclui a transmissão de dados e é um dentre vários estados possíveis. O elemento de ajuste de limite recebe o status de frame e o estado corrente e ajusta um setpoint de controle de potência em resposta aos mesmos. o setpoint é usado para controlar a qualidade de sinal do sinal de entrada e é ajustado de acordo com um esquema de ajuste específico selecionado dentre vários esquemas de ajuste possíveis associados a um respectivo estado possível.
