Abstract

Accurate ranging or localization in non-line of sight conditions is still an open research problem. Non-line of sight conditions usually introduce a positive bias in the ranging measurement that has to be corrected before accurate localization can be achieved. In order to correct this bias, the non-line of sight channel (or path) has to be characterized and known a priori. In this paper, we characterize non-line of sight paths in a residential environment using commercial off-the-shelf 802.15.4a radios. The aim is to determine how different line-of-sight and non-line-of-sight paths are by considering the variation of amplitude of deterministic multipath components extracted from channel impulse responses. The results from the measurement campaign show that the variation in amplitude of the deterministic multipath components in non-line-of-sight conditions is similar to line-of-sight conditions if the signal path is obstructed by walls only. However, if the obstruction is more complex, it is shown that the amplitude variation and range variation is much higher and the non-line of sight bias increases significantly.
