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 cana-les directos como en los inversos. Se usan técnicas para compensar los despliegues de LMU poco densos donde las secciones de la zona de servicio (J-TDOA están limitadas por demodulación de enlace ascendente o descubrimiento de bauza de enlace descendente.
