Abstract
MéTODO E EQUIPAMENTO PARA CONTROLE DE DIVERSIDADE DE RECEPçãO EM COMNICAçõES SEM FIO A diversidade de receptor em um dispositivo sem fio é controlada em resposta às condições operacionais, exigências de transmissão, e configurações de controle. O controle da diversidade reduz o consumo de energia ativando a diversidade de recepção em condições determinadas. As condições operacionais, as exigências de transmissão e as configurações de controle são utilizadas separadamente ou em conjunto para determinar se benefícios da diversidade de recepção de múltiplas antenas, tais como maior capacidade de link, maior rendimento de dados, menor energia de transmissão e menor taxa de erro, garantem o maior custo de energia da diversidade.
