“…Other authors have proposed stochastic propagation models that capture both small-and large-scale random fluctuations [8][9][10][11]; these types of models are sometimes called "dynamic models" [8][9][10]. For the indoor frequency selective channel, Nielson et al [9] represent the power delay profile (PDP) as a superposition of path clusters.…”

“…The large-scale random fluctuations are modeled by letting the value of the PDP for each bin change over time according to an autoregressive random process. The other authors [8,10,11] associate with each path or delay a random time of "birth" when the path first appears, and a random time of "death" when it disappears. Newton et al [10] used a modified Poisson process to determine which PDP bins are occupied, and empirically based distributions to model path strengths and lifetimes.…”

Statistical channel models based on BER performance are presented for a frequency-and time-selective vehicle-to-vehicle wireless communications link in an expressway environment in Atlanta, Georgia, where both vehicles traveled in the same direction. The models are developed from measurements taken using the direct sequence spread spectrum (DSSS) technique at 2.45 GHz. A collection of tapped delay line models, referred to as a "partitioned" model in the paper, is developed to attempt to capture the extremes of BER performance of the recorded channel. Overall and partition models are compared to the recorded channel in terms of the BER statistics obtained when the channels are inserted in a dedicated short range radio (DSRC) standard simulation system. The quality of the match between synthesized and recorded channel BER statistics is analyzed with respect to type of modulation (fixed or adaptive), the frame length, and the length of the interval over which the BER was calculated.
