Multiresolution time domain modeling for large scale wireless communication problems

The time domain modeling of large scale cosite interference problems, arising in wireless communication channel analysis and design studies, is discussed. It is pointed out that the use of the conventional finite difference time domain method for the treatment of such problems typically results in long, computationally burdensome simulations that limit the ability of this technique to provide an efficient CAD-oriented tool for commercial and military applications. For the purpose of accelerating these simulations, the use of wavelet based time domain solvers along with parallelization techniques is proposed.
