Modeling and evaluation of error flow characteristics in the Nakagami fading channel

The design of a data communication system using a channel with additive and multiplicative interference presents a rather difficult problem. The fading process is usually exponentially correlated, but have a variety of the probability density functions (PDF) (Nakagami, lognormal, gamma etc.). Therefore it is rather difficult to achieve analytical results on the estimation of different modems performance in such a channel. The only way to choose the modem properly consists of simulation of the so called coding channel including the modem and the continuous channel itself, i.e. practically the simulation of the error-flow corresponding to a certain pair of the modem and continuous channel with specific fading PDF. We consider a new approach to modeling of the coding channel based on the description of the fading process as a solution of a nonlinear stochastic differential equation with the required PDF and approximately exponential correlation
