Non-geometric correlated channel fading model with linear complexity

Abstract

Simulations are an important component for the investigation of wireless technologies. Thereby, a compute efficient channel model is needed for simulations of the physical layer. For the investigation of packet duplication a fading model with correlated channels is of high importance. We propose such a complexity-optimized fading model whose parameters fading strength, autocorrelation and channel correlation can be adjusted with fine granularity. The model is based on the sum of sinusoids method and includes Rayleigh distributed small scale fading and normal distributed large scale fading. The model is validated for its mathematical properties within a wide parameter range and its source code is published.
