The Computational Reduction and Performance Evaluation for the Simulation of Fading Communications Channels

摘要

Two computational reduction methods for the simulation of multiple independent Rayleigh fading waveforms are analyzed and tested in this paper. The performance evaluation using different quality criteria shows that the table lookup method increases the second order moment of the simulated power spectral density considerably unless the size of lookup table is sufficiently large whereas the linear recursion method always provides both computational efficiency and performance acceptance.
