The generalized Suzuki model of the multipath fading channel

Opis

The dataset contains the results of simulations that are part of the research on modelling the multipath fading in the communication channel.  The generalized Suzuki fading envelope is generated using the Monte-Carlo simulation (MCS) in the LabVIEW programming environment.

The Suzuki distribution is used to modelling the envelope of the received land mobile channels in an urban environment. The mobile channels modelled by the Suzuki process include multipath propagation and shadowing. The generalized Suzuki model of communication channel is described by a composite distribution that combined the Weibull short-term fading and lognormal distribution that is usually used to represent the long-term characteristics of the mobile radio channel. Using the conditional probability rule, we obtain the generalized Suzuki distribution expressed by Equation (1). The parameter of the Weibull distribution r0 is explained by equation (2). The model of generation of the generalized Suzuki envelope is described by Equation (3).

The MCS provides a general approach to numerically approximating the distribution function for the value of the output quantity Y(t) = f(X)  (where Y(t) is a single (scalar) output quantity. X represents the N input quantities (X1(t), . . . ,XN(t))T .

The inputs to the Monte Carlo simulation procedure are:

- the model Y(t) = f(X),

- the probability density functions for input quantities X1(t), . . . ,XN (t),

- the number M of Monte Carlo trials.

The probability density functions for X1(t)=X2(t), and X3(t)= N(t) are Gaussian type. The number of Monte Carlo trials is equal to 100 000. The exemplary simulation results are shown in Fig. 1.

The simulations were carried out for the Weibull variance equal to 0.5 (Equation 4) and the mean of the lognormal distribution equal to 1. The variable parameters of simulations are the shape parameter of the Weibull distribution and the standard deviation of the lognormal distribution.

The attached files contain two columns related to fading envelope: the number of samples and the amplitude of fading envelope in [dB] and two columns related to the histogram: the number of bins and the histogram results in percents of total amplitude. Files can be opened in both the LabVIEW software and Windows Office Notepad.

The files are described as follows: MCS_gen_Suzuki_value of the standard deviation of the lognormal distribution expressed in [dB]_value of the shape parameter of the Weibull distribution.
