Abstract

La invencion sirve para disminuir las interferencias en canales iguales en los dispositivos de recepcion de las estaciones base y las estaciones de los abonados de un sistema de radiotelefonía construido en células, en donde se aplican células de radiotelefonía con canales de radio de igual frecuencia, y la transmision de señales se lleva a cabo aplicando el proceso llamado JD-CDMA (Joint Detection - Code Division Multiple Access - Deteccion Conjunta - Acceso Multiple de Division de Codigo), en donde se desarrollan un numero de conexionesutiles paralelas en una banda de frecuencia elevada, para lo cual se descodifican nuevamente las señales utiles con un codigo de ampliacion diferente, ampliado alrededor de un factor determinado en el eje de frecuencia y en el lugar de la recepcion aplicando este codigo de ampliacion. En una célula de radiotelefonía se toman en cuenta, en los correspondientes dispositivos de recepcion al descodificar, al menos en parte, los codigos de ampliacion que al menos se usan en otra célula de radiotelefonía aplicando la misma banda de frecuencia. La invencion permite aplicarla en futuros sistemas moviles de radiotelefonía de CDMA.
