Propagation Characteristics and Modeling Simulation of Signals in Wireless Channels

Abstract

This thesis studies the related performance of the hot-research wireless communication systems based on the fading phenomenon of signals in wireless channels, mainly introduces several typical cases of signal fading in the channel, studies the problem of signal attenuation loss, and carries out the Free space propagation Model, the modeling and simulation of the logarithmic path propagation loss model and its modified logarithmic normal shadow path loss model, and analyze the results of these models. In order to realize the construction of a better wireless communication system, according to the analysis of the results of the fading model of the signal in the channel, this thesis also simulates the Okumura model to predict the field strength of different terrains, and combines the correction of the model by Hata to analyze the propagation of radio waves in the wireless channel.
