Abstract :
The propagation channel of wireless indoor networks can be modeled as a linear filter with a complex-valued impulse response. Due to the effect of indoor multipath fading, this linear filter is characterized by three sets of random variables-path arrival times, path amplitudes and carrier phase shifts. This paper discusses a simulation model for the distribution of path arrival times based on the modified Poisson or Δ-K model. We present a discrete-time non-homogeneous Markov description of the arrival process, and present results indicating potential improvements in estimation of the model parameters. We then describe an implementation of the model using the Ptolemy simulation environment which can be used for evaluation of wideband wireless indoor communication links
