Design and Implementation of Signal Processing Scheme in CDMA Wireless Location Systems

摘要：

Subscriber radiolocation techniques for code division multiple access (CDMA) cellular networks has been studied extensively in recent years. The networkbased angle of arrival (AOA), time difference of arrival (TDOA), and time of arrival (TOA) techniques offer solutions to the position estimation problem. In this paper, The signal processing scheme of wireless location system based IS-95 is presented, in which TOA of reverse access channel transmissions is measured using sub-correlation detection algorithms and TOA estimation accuracy is improved using second search. Furthermore, reverse access channel decoding is implemented used to identify access channel message type, mobile identification, and dialed number.
