In a network-based Wireless Location System (WLS), geo-graphically distributed Location Measurement Units (LMUs) must be able to detect and use reverse channel (mobile to network) signals across multi-ple BTS coverage areas. By using Matched Replica correlation processing with the local and reference signals subdivided into discrete segments prior to correlation, the effects of mobile clock drift and Doppler shifts can be mitigated allowing for increased processing gain.

Dans un système sans fil basé sur un réseau (WLS), des unités de mesure de localisation distribuées géographiquement (LMU) doivent pouvoir détecter et utiliser des signaux de canal inverse (mobile vers réseau) sur de multiples zones de couverture BTS. En utilisant un traitement de corrélation de réplique correspondant aux signaux locaux et de référence sous-divisés en segments discrets avant la corrélation, les effets du décalage dhorloge mobile et des décalages Doppler peuvent être atténués, ce qui permet une augmentation du gain de traitement.
