Abstract

"PROCESSO E DISPOSITIVO DE COMUNICAçãO COM DIVERSIDADE DE TRANSMISSãO EM UMA ESTAçãO BASE". Um processo de comunicação STD(Diversidade de Transmissão por Seleção). No processo, uma estação base seleciona uma antena de transmissão correspondendo a um sinal de seleção de antena recebido de um terminal, transmite um sinal de canal de tráfego através da antena, e transmite uma predeterminada parte do sinal de canal de tráfego através de uma antena não selecionada.
