Abstract

MéTODO E APARELHO PARA TRANSMITIR UM SINAL EM UM SISTEMA DE TELECOMUNICAçãO SEM FIO, REDE E EQUIPAMENTO DE COMUNICAçãO, E, PRODUTO DE PROGRAMA DE COMPUTADOR Um sistema para transmitir um sinal via antenas de diversidade (60, 70; 150, 160, 170, 180; 190, 200) incluir: pelo menos um elemento de retardo (100) para gerar pelo menos uma réplica retardada do sinal sujeito a certo retardo; o sinal e pelo menos uma réplica retardada sendo adaptados para serem transmitidos via as antenas de diversidade (60, 70; 150, 160, 170, 180; 190, 200), e uma unidade de controle (110) para o pelo menos um elemento de retardo (100) para variar (110) o certo retardo (100), por meio do que o sinal e pelo menos uma réplica retardada, transmitidos via as antenas de diversidade (60, 70; 150, 160, 170, 180; 190, 200), dão origem à combinação alternada construtiva e destrutiva entre eles.
