1. A method for estimating angle information of an ultra-wideband radio signal, the method comprising:
receiving, by means of at least one receiver antenna of a receiving device, said ultra-wideband radio signal,
deriving a channel impulse response of a propagation channel of said received ultra-wideband radio signal or an envelope function indicative of an envelope of said channel impulse response,
acquiring, by means of a sensor, sensor information indicative of a state of said receiving device, and
deriving, by inputting said channel impulse response or said envelope function into a neural network, an angle information probability distribution for said ultra-wideband radio signal, wherein the sensor information indicative of the state of the receiving device is also input into the neural network to improve the accuracy of the angle information probability distribution.
