Grey Model with Rolling Mechanism for Radio-Wave Path-Loss Forecasting in Suburban Environment

The grey prediction model, GM (1,1), with the property of processing with a minimum of data, has been successfully applied in various fields. However, applying grey prediction with rolling mechanism (GPRM) to predict radio-wave path-loss has not been widely investigated. Thus, this paper aims applying GPRM approach for the prediction of radio-wave path loss in suburban environment. Furthermore, a comparison has been discussed with traditional other radio-wave path-loss prediction approaches and the proposed approach. An illustrative example, we find that the GPRM method can effectively fitting the actual value than other current models. Consequently, this method can help designer to evaluate radio-wave path-loss in uncertain environment.
