Fusion Prediction Model of Broadcast Radio Signal Propagation Based on the Coefficient of Variation Method

Abstract

To support the planning and development of broadcasting, we first develop a novel fusion prediction model by introducing the coefficient of variation method (CVM) in radio wave propagation prediction to enhance the accuracy of the broadcast propagation model and reduce the complexity of the fusion modeling method. The main contributions of this paper are as follows: (1) The CVM is introduced into the field of channel modeling for the first time, and a fusion modeling approach with high accuracy and low complexity based on this method is proposed. (2) A systematic analysis of the CVM and the fusion modeling approach is conducted, establishing a fusion channel model based on an improved CVM. Experimental results indicate that compared to the ITU-R P.1546, ITU-R P.2001, and ITM models, the improves the prediction accuracy of the proposed by 50.39%, 60.47%, and 55.98%, respectively.
