Abstract

"`REPETIDORA DUPLEX POR DIVISãO DE TEMPO PARA USO EM UM SISTEMA CDMA". Trata-se de um método e de um aparelho que repete de modo duplex de divisão de tempo (TDD) um sinal de espectro por programação, sendo que o dito sinal de espectro por programação compreende uma série de símbolos de código modulados com uma sequência de pseudo-ruídos (PN). A repetidora TDD recebe de modo intermitente o sinal de espectro por propagação em um local remoto de uma fonte que fornece o sinal de espectro por programação. A repetidora TDD amplifica e atrasa o sinal de espectro por propagação recebido por uma proporção predeterminada. A repetidora TDD transmite de modo intermitente o sinal de espectro por propagação recebido amplificado atrasado, de tal modo que a TDD não esta recebendo o sinal de espectro por propagação quando está transmitindo a energia do sinal.
