1. A method for determining the channel gain(s) between one or more emitter(s) and one or more receiver(s), the method comprising the steps ofemitting a first output signal by means of a first emitter, the first output signal being deterministic and containing an interval of frequencies, receiving a first input signal by means of a first receiver, determining a transformed first input signal by transforming said first input signal by means of a predetermined linear transform, determining a first channel gain by means of comparison of said transformed first input signal and a predetermined original first signal being equal to said first output signal being emitted and received noiselessly with a known channel gain and being transformed by means of said linear transform, determining the original first signal from an obtained measure of noise applied to the first input signal, said measure of noise being obtained from a comparison of a prior transformed first input signal and the respective prior original first signal.
