In wireless sensor networks, the positioning scheme using the received signal strength (RSS) has been widely considered due to its simplicity. Appropriate estimation of path-loss exponent (PLE) between a sensor node and an anchor node plays a key role in reducing position error in this RSS-based positioning. In the conventional researches, a sensor node directly uses the PLEs given by its neighboring...
In this paper, we propose a new approach on DOA estimation under the number of signal sources is unknown. This can be applicable even to the case of fully correlated sources for which existing algorithms such as AIC and MDL are not workable. AIC and MDL are well-known ldquoinformation theoretic criterionrdquo algorithms for estimating the number of sources observed by a direction finding array. In...
