Abstract
El presente invento trata de superar el problema de audibilidad en redes de comunicaciones de acceso múltiple por división de códigos en las que servicios de posicionamiento son proporcionados, utilizando un dispositivo de muestreo 204, 205, 206 separado para cada transmisor 201, 202, 203, que envía al dispositivo de computación 208 una representación de las senales transmitidas solo por ese transmisor. Una correlación cruzada de la representación enviada devuelta por el terminal móvil 207 con la representación enviada devuelta por el dispositivo de muestreo en el transmisor más sobresaliente es efectuada en el dispositivo de computación 208, y una estimación de esa senal más sobresaliente es sustraída de la representación enviada devuelta por el terminal móvil 207 a fin de reducir su efecto en las senales remanentes tanto como sea posible. Las etapas de correlación cruzada y sustracción son repetidas hasta que no queden senales útiles a ser extraídas.
