Abstract

En un sistema de localización inalámbrica de superposición, basado en U-TDOA, se usan LMUs típicamente correlacionadas con BTSs para recoger señales radio tanto en los canales directos como en los inversos. Se usan técnicas para compensar los despliegues de LMU poco densos donde las secciones de la zona de servicio U-TDOA están limitadas por demodulación de enlace ascendente o descubrimiento de bauza de enlace descendente.
