Simulation for Correlated Rayleigh Fading Channels by FIR Pulse-Shaping Filtering

摘要

This paper addresses a method for the generation of the correlated Raleigh distributed fast fading by FIR pulse- shaping filtering. The coefficients of FIR filter equal to the samples of the square root of the well-known U-shaped Power Spectral Density (PSD). An analysis of the statistical properties of FIR-based method for correlated sample generation is presented in detail. Simulation shows the approach is higher efficient and more straightforward than other correlated Rayleigh generation methods e.g. the well- known improved Jakes'' Model proposed by Pop and Beaulieu.
