  • Method and device for simulating a radio channel
    Patent number: 7430413
    Abstract: The invention relates to a device and a method for simulating a radio channel, wherein a signal transmitted and received by more than one antenna is simulated. The method comprises supplying an input signal of each antenna to a similar delay line, each delay line comprising a delay element connected in series for each propagation path, weighting an output signal of the delay elements corresponding with each propagation path by a term in dependence of a control vector of each transmitting antenna, by a term describing the distortion of a propagation path, and by a term in dependence of a control vector of each receiving antenna, and adding up the components corresponding with each receiving antenna and obtained from the outputs of the weighting means.
