Electromagnetic interference in wireless communications: behavioral-level simulation approach

The main challenges in electromagnetic interference (EMI) modeling and simulation for modern and future wireless communication systems and networks, taking into account nonlinear interference effects, are discussed in this paper. It is emphasized that there exists a big difference between simulating analog and digitally-modulated systems when spurious nonlinear effects in the hardware are included. A computationally-efficient approach for the EMI analysis of wireless systems and networks by behavioral-level numerical simulation is proposed. The rapid growth of PC computational power allows us to implement a full-scale simulation of modern wireless systems and networks at the behavioral level at reasonable cost. This technique can be used for simulating optical communication systems as well.
