A sum-of-sinusoids based simulation model for the joint shadowing process in urban peer-to-peer radio channels

Most conventional channel models are not capable of capturing the joint spatial correlation of shadowing processes between a large number of meshed radio channels in an ad-hoc wireless communications network. In this paper, we present a sum-of-sinusoids (SOS) based simulation model for the joint shadowing process in urban peer-to-peer radio channels. The performance of the proposed channel simulator is analyzed in terms of the autocorrelation and joint correlation function of the simulated shadowing process. Simulations illustrate that the proposed model is able to generate deterministic output shadowing values with a Normal distribution (in dB) and desired correlation properties. It is thus suitable for use in system level simulations, such as the evaluation of routing and radio resource management algorithms in ad-hoc networks.
