Abstract

In this paper, we investigate the fundamental loss of ranging resolution using received signal strength indicator (RSSI) observations relative to unprocessed received signal (URS) measurements. Unlike previous work, this is done for a single propagation model that accounts for large-scale (log-normal) fading and small-scale (multipath) fading effects. Further, this contribution fully accounts for the temporal correlation of the log-normal attenuation and the multipath channel, which previous work has ignored. Cramer Rao bounds on the estimates of range will give us a complete description of the effects of data reduction (through RSSI observations), multipath, and random attenuation on the estimates of range.
