Abstract :
The technological state of the art and future trends of high-speed digital mobile communications are discussed. Mobile radio transmission performance for high-speed digital signals is reviewed and specified. The selective fading propagation model, which describes dynamic changes in received signal levels and frequency characteristics, is reviewed, and a novel model is proposed. The characteristics of two-branch diversity and of a decision feedback equalizer employing the Kalman filter algorithm are shown by means of computer simulations
