Abstract

"MéTODO E EQUIPAMENTO PARA AJUSTAR VALOR DE REFERêNCIA DE CONTROLE DE POTêNCIA EM UM SISTEMA DE COMUNICAçãO SEM FIO". Trata-se de técnicas para ajustar o valor de referência (setpoint) de um loop de controle de potência em um sistema de comunicação sem fio. O valor de referência pode ser ajustado com base no status do quadro indicativo de quadros decodificados suprimidos/de boa qualidade, em uma ou mais métricas (tipicamente suaves) indicativas da confiança nos resultados decodificados, no excedente/déficit de potência indicativo da diferença entre a qualidade do sinal recebido e o valor de referência e uma E~ b~/N~ t~ limite necessária para o nível desejado de desempenho, ou em uma combinação dos mesmos. As métricas podem incluir taxa de erros de símbolo reencodificada (re-encoded), medida de potência recodificada, medida Yamamoto modificada, LLR mínima ou média entre os bits decodificados, várias iterações de decodificação e possivelmente outros. O valor de referência pode ser ajustado de maneiras diferentes e/ou em quantidades diferentes dependendo dos fatores acima referidos. As técnicas podem ser empregadas para links direto e/ou reverso em sistemas CDMA.
