A crosstalk-resilient method for time-of-arrival measurement

A method for crosstalk detection and removal in multichannel time-of-arrival measurement systems is proposed. The method, based on low-complexity processing of cross-correlation results, is evaluated by numerical simulations and experimental characterization. Results show the capability to detect and remove crosstalk by processing the signals acquired by two mutually-interfering electrical channels. The validation, carried out on a time-of-arrival positioning system, yielded centimeter-level accuracy in the presence of relevant inter-channel interference. The proposed method is of a general nature and is not limited only to positioning scenarios.
