Prediction of Fading

In this research project we investigate the possibility of predicting the complex radio channel ahead in time when the terminal is moving in a straight line. The Doppler spectrum and the amplitude of the complex scatterers are determined using an ESPRIT-type algorithm, and the signals are then extrapolated into the future assuming that the scatterers remain constant. Synthetic and real data (from a sub-urban environment) both indicate that for a large number of scatterers, a continuous Doppler spectrum, the signal may be predicted about a wavelength ahead.
