Wireless Channel Modeling and Simulation with K Distribution

We study modeling of wireless channel with fading and shadowing effects using K distribution with modified Bessel function of the second kind with half integer order. This allows us to obtain probability density function and cumulative distribution function in closed form in terms of elementary functions and simplifies the calculation of exact average bit error rate. The problem of Monte Carlo simulation using random variables with K distribution is also addressed. © 2020, Springer Nature Switzerland AG.
