Title
Geolocation using Transmit and Receive Diversity
Abstract
Geolocation using received signal strength (RSS) has large errors due to multipath fading (fading results in high variations in RSS). We show how and when spatial diversity combined with channel knowledge at the receiver can be used to combat fading effects to increase accuracy in location estimate. We then propose a simple scheme for distance estimation, characterize the channels for which improvement in distance estimates can be thus obtained and prove that mean square error of distance estimate converges to zero with increasing diversity order. It is observed that the improvement can always be obtained for Rayleigh channel, and for Nakagami- channel if the parameter remains the same regardless of the distance.
