Abstract :
An enhanced method of generating a shadow fading for mobile radio channel simulation is proposed. It is verified that simulated samples satisfy the properties of variance, autocorrelation and cross-correlation. The proposed channel simulation method can be utilized for evaluating the performances in mobile communication systems where the exchange of interactive information between uplink and downlink channels is required.
