Abstract

RECEPTOR CDMA. MéTODO PARA OPERAR O RECEPTOR CDMA, RECEPTOR POSSUINDO UM Nó DE ENTRADA ACOPLADO A UMA PLURALIDADE DE ANTENAS RECEPTORAS, E, PROGRAMA DE COMPUTADOR. Uma estrutura de equalização a nível de chip é descrita para um sistema de arquitetura de múltiplas antenas de transmissão e recepção, que é adequada para uso no enlace descendente WCDMA. A estrutura do equalizador leva em conta a diferença nas naturezas da interferência da antena interna e na interferência de acesso múltiplo e suprimi a interferência da antena interna e a interferência de acesso múltiplo (MAI). Um desempenho do receptor melhorado é alcançado com ma complexidade de implementação razoável. O uso da arquitetura do receptor CDMA, de acordo com esta invenção, possibilita a realização das taxas de dados aumentada para o usuário final. A arquitetura do receptor CDMA pode também ser aplicada em conjunção com as arquiteturas do sistema de diversidade de transmissão espacial-temporal (STTD).
