Abstract
Provided are a wireless communications node (WCN) and a method therefor achieving mitigation of multipath interference via optimized estimation of coordinate location of the WCN relative to wireless communications with a plurality of reference points (RPs). To do so, the WCN effects a constrained gradient descent with respect to phase ranging measurements to one or more of the plurality to minimize a cost of error associated with the obtaining of such measurements.
