Abstract

"DISPOSITIVO E PROCESSO DE TRANSMISSãO E DE RECEPçãO EM UM SISTEMA DE COMUNICAçãO MóVEL". Um dispositivo transmissor de diversidade de tempo em uma estação base de um sistema de comunicação móvel. O dispositivo transmissor possui uma pluralidade de antenas de transmissão, tantos transmissores de RF (Rádio Freq³ência) quantas forem as antenas de transmissão e conectados às suas correspondentes antenas de transmissão para dar saída e sinais sobre um enlace avante, um controlador para gerar um sinal controlador de comutador em um ciclo de tempo não-sobreposto, um modulador ortogonal para modular um sinal transmitido por um código ortogonal, um espalhador para espalhar a saída do modulador ortogonal, e um comutador conectado a um terminal de saída do espalhador, para conectar a saída do espalhador a um correspondente transmissor baseado no sinal de comutador. De acordo com outra caracterísitica da presente invenção, um dispositivo receptor em uma estação móvel de um sistema de comunicação móvel possui um receptor de canal para detectar um sinal de canal piloto proveniente de um sinal de entrada de enlace avante e gerar valores estimados de fases e de tempo, um controlador para gerar uma seleção de sinal de controle baseada na informação de ciclo e na informação padrão de comutação, em sincronização com um tempo de referência para uma estação base, um seletor para seletivamente dar saída aos valores estimados de fase e de tempo recebidos do receptor de canal piloto baseado na seleção de sinal de controle, e um receptor de canal de tráfego para detectar um sinal de canal de tráfego em uma selecionada posição de tempo estimado e corrigir um erro de fase do sinal detectado de canal de tráfego baseado no valor estimado de fase, para decodificação de sinal.
