SYSTEMS AND METHODS FOR PRECISE RADIO FREQUENCY LOCALIZATION USING NON-CONTIGUOUS OR DISCONTINUOUS CHANNELS

摘要

Systems and methods for determining locations of wireless nodes in a network architecture are disclosed herein. In one example, a method for localization of nodes in a wireless network architecture includes receiving, with processing logic of a first wireless node having a wireless device, a RF signal from a second wireless node having a wireless device, measuring, with the first wireless node, first channel state information of a first frequency channel of the RF signal, and measuring, with the first wireless node, second channel state information of a second frequency channel of the RF signal with the first and second frequency channels being non-contiguous or discontinuous channels. The method further includes determining delay profile estimation between the first and second wireless nodes based on the first and second channel state information without phase alignment.
