Examples relate to a method for performing multi-carrier phase-based ranging between two radios including: i) calculating squared channel responses based on channel measurements between the two radios for a plurality of available carriers within a measurement band for the phase-based ranging, where the measurement band has at least one band gap each with one or more unusable carriers for calculating squared channel responses, ii) estimating, via a trained neural network, squared channel responses for the unusable carriers in a respective band gap from squared channel responses of carriers adjacent to the respective band gap, and iii) estimating a distance between the two radios based on both the calculated and estimated squared channel responses.

Multi-carrier phase difference distance estimation

Example embodiments relate to methods for estimating a location of at least one mobile network node and respective network. An example method for estimating a location of at least one mobile network node of a wireless communication network including the at least one mobile network node and at least two static network nodes includes performing initial range measurements between the at least two static network nodes in a pairwise manner. The method also includes determining an initial location estimate. Additionally, the method includes determining an estimate for corresponding noise samples. Further, the method includes estimating corresponding initial parameters of a Gaussian mixture noise model. In addition, the method includes determining a weighted sum of respective refined parameters of the Gaussian mixture noise model and the corresponding initial parameters of the Gaussian mixture noise model.
