Statistics of Sampled Rician Fading
Abstract
Realizations of the channel impulse response function generated with Rician amplitude statistics have been used for many years to evaluate system performance in the regime between full Rayleigh fading and ambient non-fading conditions. While it is well known that Rician distributed realizations fail to match observed phase fluctuations, Rician statistics provide a worst case description of the occurrence of deep fades. Thus the use of Rician statistics is attractive in slow fading situations where system performance has been rendered insensitive to phase variations. The purposes of this report are to provide new information on the temporal statistics of Rician fading (mean fade duration and separation) and to determine sampling requirements on realizations of the channel impulse response function with Rician amplitude statistics. It is found that 400 decorrelation time tau sub 0 realizations generated with 10 samples per tau sub 0 and sampled at (tau sub 0)/40 accurately reproduce the temporal statistics of Rician fading..
