چکیده مقاله
This paper propose an improvement land mobile satellite mimo channel model by definition second order environment interactions calculation in the quasi deterministic radio channel generator QuaDRiGa model In the other word, in addition to line of sigth LOS interactions and non line of sight single interaction clusters NLOS_SICs , the new channel model will be included a kind of non line of sight multiple interaction clusters NLOS_MICs known as non line of sight twin interaction clusters NLOS_TICs Hence, more details of delay spread, powers, departure and arrival angles are involved in the channel coefficient computations Summary, when the clusters formed by the means of parametrising large scale parameter LSP , the cluster types recognition approach used to determining clusters type and then for each of them, different methods used to calculate channel parameters A corresponding matlab simulation model proposed and the impact of specify cluster types on the azimuth and elevation, delay spread and power delay profile is discussed Finally, experimental result and numerical analysis e g shadow fading, K factor delay spread shows that the proposed channel model is able to serve as a more accurate design framework for land mobile satellite Multiple input_Multiple output MIMO channel model and have a better performance than previous QuaDRiGa
