Abstract

"MéTODOS DE DETERMINAR CARACTERìSTICAS DE UM SINAL TRANSMITIDO EM UM RECEPTOR DE UM SISTEMA DE COMUNICAçãO E ESTIMAçãO DE CANAL EM UM RECEPTOR DE UM SISTEMA DE COMUNICAçãO, RECEPTOR DE UM SISTEMA DE COMUNICAçãO, E, SISTEMA W-CDMA". é proposta uma técnica para determinar parâmetros, especialmente a estimação de canal, no receptor de um sistema de comunicação utilizando técnicas de antena auto-adaptável. A técnica utiliza informações transmitidas nos sinais de antena e nos sinais de feixe para determinar os parâmetros.
