Abstract :
Indoor and outdoor field trial measurements are used to validate the autocorrelation function derived in an exact manner for the Weibull fading signal. In addition, an accurate closed-form approximation to the power spectrum of the Weibull envelope is obtained and also validated. Comparisons are performed and an excellent fit to the field measurements is found.
