Sum-of-Sinusoids-Based Fading Channel Modeling And Analysis In Vehicular Ad Hoc Networks

Armed with the knowledge of network environment about Vehicle Ad Hoc Networks (VANET) and understanding of communication system propagation mechanism and its modeling method, this paper established two kinds of sum-of-sinusoids-based simulation models based on a reference model for VANET network environment:statistical simulation model and deterministic simulation model. Subsequently, the statistical characteristics expressions of each model are derived, including the time-domain autocorrelation function and variance of autocorrelation of the complex envelope. Next, for various models, we analyzed the change rules of statistical characteristics under various network channel parameters and then compared the newly proposed models with the referenced model. At last, this paper compared the proposed models with the existing model to prove the advantages and disadvantages of these models.The main contributions and innovative points of this study are as follows:(?) Integrated with the analysis of single mobile node channel model in cellular network and proposed a referenced model for double mobile nodes channel in VANET, whose statistical characteristics are derived.(?) Established two kinds of channel simulation models based on the previous referenced model:statistical simulation model and deterministic simulation model.(?) Derived the statistical expressions of statistics for various models, these characteristics are used for comparative analysis in the following research.(?) Analyzed the change rules of various statistical characteristics for various network parameters in view of all the proposed models and compared them.
