Method for determining the position of a transmitter without using a reference path

摘要

The method involves expressing a complex observation vector (E0) with a specific dimension using a complex scalar coefficient and using a complex vector model. A joint estimate criterion is defined (E1) for a set of nuisance parameters and a position value. The parameters are estimated (E2) by minimizing the joint estimate criterion for a given position of a transmitter e.g. fixed transmitter. A set of values obtained for the nuisance parameters is utilized (E4) in the estimate criterion, and the position value is estimated using measurements corrected according to a specific formula.
