WIRELESS LOCATION SYSTEM

摘要

A wireless location system uses a statistical approach, in which a probability distribution is trained that relates reliable observations of a signal parameter to a known measure of location. The probability distribution is then used to locate a mobile transmitter when addition observations are available. Various precise wireless location techniques may be used to train the distribution or may be used alone to locate the mobile transmitter. In one wireless location technique, a wireless location algorithm uses weighted observations, where the observations are weighted with received signal strength.
