Abstract : Design of communication systems can be facilitated using channel modeling. Physical characteristics of the channel can be observed with the help of channel models. Land Mobile Satellite(LMS) channel is a complex communication channel with many factors influencing the channel. The ionospheric, tropospheric effects along with mobility of the user equipment are some of the parameters that make the LMS channel model unique. In this work, dual polarized MIMO channel is considered for better capacity. Widely used dual polarized LMS MIMO channel models are Quasi Deterministic Radio Channel Generator(QuaDRiGa) and Loo. QuaDRiGa is a geometric statistical channel model which incorporates continuous time evolution. Loo is a statistical model which can analyze second order statistics of the channel like level crossing rate (0.001-0.5) and average fade duration (0.001-1 s). Thus the models have best captured the ionospheric, troposheric and fading effects for a LMS system. © 2017 IEEE.
