Abstract :
In mobile communications, the received signal level of a wide-band transmission differs from that of a narrow-band transmission. Only a few studies have been done to clarify the received signal-level characteristics of a wide-band transmission. In order to normalize the signal-level distribution we propose a new propagation parameter called the equivalent received bandwidth 2ΔfΔLmax which is a product of the received bandwidth 2Δf and the maximum difference in the propagation path length ΔLmax. We evaluated the relation between this new propagation parameter and the fading depth by computer simulation, and we found they are closely related. Further, we have examined the received signal-level autocorrelation dependence on the received bandwidth and difference in path length, theoretically and by computer simulation. The result showed that the autocorrelation was independent of both
