An Efficient FWGN-Based Modelling And Simulation Scheme For The Suzuki Flat Fading Channel
Journal Title: IOSR Journal of Electronics and Communication Engineering(IOSR-JECE) - Year 2018, Vol 13, Issue 2
Abstract
This paper optimizes the FWGN-based Suzuki fading stochastic model for the frequency-nonselective land mobile radio channel as this composite Rayleigh-Lognormal distribution represents the worst-case fading. In a previous work, the Young & Beaulieu simulator was identified to be a better Rayleigh channel model. The lognormal fading generator is then optimized through the study of various digital filters allowing the choice of the best compromise considering the environment, required fading statistics and shadowing severity level. Both Finite and Infinite Impulse Response filters are evaluated. Filters discrimination criteria are the magnitude and phase responses, the minimum required order and thus hardware implementation cost, the shadowing outage probability and autocorrelation, as well as the statistical divergence between the simulated and theoretical shadowing distributions in LTE environments. The Bhattacharyya distance is therefore computed using a Monte Carlo method. The proposed Suzuki fading simulator, its output signal and various order statistics are finally presented.
