Abstract

"MéTODO PARA PROCESSAMENTO DE SINAL NO EQUIPAMENTO DO USUáRIO DE SISTEMA DE COMUNICAçãO MóVEL CDMA". A invenção revela um método de processamento de sinal para equipamento de usuário em um sistema de comunicação móvel CDMA. O método de processamento de sinal é uma combinação da diversidade de tempo com detecção de junção de modo a aumentar o ganho de diversidade do receptor. O método compreende: amostrar um sinal recebido no domínio de tempo, estimar o valor da resposta de impulso de canal espacial, obter matrizes, constituir uma matriz do sistema, executar o algoritmo de detecção de junção e obter um valor estimado dos dados de envio originais. Quando o método é utilizado em um equipamento do usuário móvel, o problema de não correspondência de performance do enlace ascendente e do enlace descendente pode ser resolvido, utilizando a mesma freq³ência, a multiplexação pode ser alcançada e o algoritmo de detecção de junção é mais simples. O método também pode ser utilizado em uma estação base.
