Abstract
"MéTODO PARA MODIFICAR UM NìVEL DE POTêNCIA DE TRANSMISSãO DE UMA ESTAçãO MóVEL E ELEMENTO DE INFRA-ESTRUTURA, AMBOS EM UMA REDE DE COMUNICAçãO SEM FIO". Um método para modificar tabelas de ganho para as comunicações de link reverso em uma rede de comunicação sem fio cdma2000 inclui as etapas de estimar a velocidade de uma estação móvel para uma dada taxa de erros de frames (FER) e taxa de dados e prover três ganhos para seleção com base na velocidade estimada de modo a especificar um nível de potência de transmissão de link reverso. A estimativa de velocidade pode ser efetuada usando-se uma técnica de cruzamento de nível, uma técnica de aproximação de covariância, ou uma técnica de estimativa de espectro Doppler.
