On the second-order statistics of a new simple model for land mobile satellite channels

چکیده
A new simple model has recently been proposed for land mobile satellite channels. In this paper we study the secondorder statistics of the new model. First we develop a characteristic function-based approach for calculating the level crossing rate of the new model in diversity systems, where the branches can have different fading statistics. Then we compare the level crossing rate and the average fade duration of the new model with measured data. Similar to the first-order statistics, our results show that the second-order statistics of the new model can be expressed in compact closed forms, convenient for both mathematical analysis and numerical calculations.

_ In this paper we propose a new shadowed Rice model for land mobile satellite channels. In this model, the amplitude of the line-of-sight is characterized by the Nakagami distribution. The major advantage of the model is that it leads to closed-form and mathematically-tractable expressions for the fundamental channel statistics such as the envelope probability density function, moment generati...

Abstract — In this paper, a new stochastic model for land mobile satellite channels is presented. From the analytical reference model, an efficient deterministic computer simulation model is derived by replacing all coloured Gaussian noise processes by finite sums of weighted sinusoids with equally distributed phases. A numerical optimization procedure has been applied in order to adapt the sta...

Introduction: A new modelling method suited to the dual circular polarised 2x2 (MIMO) channel applicable to land mobile satellite (LMS) communications in line of sight cases is presented. In this scenario, it is necessary to apply correlated fading to the co-polarised and cross-polarised channels separately in order to model the evident polarization multiplexing in such channels found from meas...
