Abstract
In a method and device, simple hardware such as a standard User Equipment (UE), a mobile telephone, is used to collect the impulse response of a radio channel. The data generated is used to classify radio channels based on the impulse response estimates by estimating distribution parameters of the impulse response. This makes it possible to distinguish between different types of fading and hence, radio environments by matching the parameters to known radio channel models.
