Abstract

In order to develop new concepts in the field of wireless communication and related areas like Inter Vehicle Communication (IVC), simulation is a standard methodology to investigate their behavior and analyze the influence of different parameters. Several factors determine the accuracy of the used simulators, especially the complexity for which they represent wireless signals, their possibilities to compute path loss influences and considerations regarding noise and interference at reception. Obtaining accurate results that takes a lot of the real-world behavior into account seems to be computational expensive. While the simulator executes a given scenario, it is difficult to further develop a concept or draw a final conclusion. So, users have to wait for the simulation results. In order to keep this time short, it is possible to simplify scenarios or give up intermediate results. Another possibility to obtain results in a shorter time can be achieved by a decrease in accuracy. But this is undesirable as it can distort the simulation results and thus manipulate the conclusions drawn on the basis of them. Finally, a rather trivial solution to this problem can be a higher speed of simulators. In order to retain accuracy but obtain a considerable speedup in the execution of simulations, I created a new wireless channel implementation. It represents signals by their spectral power density and defines efficient algorithms to perform calculations with them. The implementation is capable of handling multi-channel simulations, Adjacent Channel Interference (ACI) and a varying interferer situation during reception. Additionally, a newly introduced mechanism can avoid the computation of path loss attenuations in a way that does not influence the final results. This new approach allows to run wireless channel simulations in just a fractional part of today’s usual computation time without affecting accuracy. Developers can therefore make use of more intermediate results to work on their concepts and verify their results by more complex or a higher number of simulations.
