Abstract

The characteristics of tropospheric scatter channel is very important for the design and application of multiple-input multiple-output (MIMO) tropospheric scatter communication system. In view of the problem that the channel modeling in the existing literatures is based on the assumed fading parameters, which cannot reflect the real characteristics of the tropospheric scatter channel, a modeling method considering the actual application environment of the tropospheric scatter link is proposed in this paper. Based on the geographical elevation and tropospheric atmospheric environment data of the actual communication link, the slow fading and fast fading parameters of the basic transmission loss, time domain, frequency domain, space domain characteristics are obtained by using the prediction formula of tropospheric scatter propagation characteristics. The Kronecker model is applied to the MIMO tropospheric scatter channel and the method of determining parameters of the Kronecker model is provided. The model takes into account the actual characteristics of the tropospheric scatter channel, and can reflect the fading characteristics of the channel more truly. It can be used to analyze the performance of the tropospheric scatter communication system under various modulations and coding modes.
