DOI: 10.1007/s11277-019-06900-2
Abstract: Direct position determination (DPD) is a promising technique, which localizes transmitters directly from original sensor outputs without estimating intermediate parameters in a single step. Therefore, DPD improves the location accuracy and avoids the data association… read more here.
