چکیده
In this paper, the problem of dual polarization based MIMO Processing in Shadowed-Rician (SR) fading land mobile satellite (LMS) channels is studied. It is shown in literature that polarization is used as a interference rejection method; and, most of the existing analytical results are not in closed-form. In this paper, we derive the closed-form expressions of the moment generating (MGF) function of the received signal-to-noise ratio of the MRC based receiver in SR fading LMS channels. Then we provide closed-form expressions of the symbol error rate (SER) by using MGF approach. The analytical diversity order and capacity of the considered scheme is also derived. It is shown by by derived closed-form capacity expression that the capacity of the considered dual polarization based scheme is improved; and it is found very useful in practical satellite communication systems.

Optimized Behaviour of MIMO System under Different Equalization Techniques and Modulation Schemes over Rayleigh and Rician Fading Channels
Wireless communications using Multiple-Input Multiple-Output (MIMO) links has emerged as one of the most significant breakthroughs in modern communications because of the huge capacity and reliability gains promised even in worst fading environment. This paper presents the optimized behaviour of MIMO systems over Rayleigh and Rician Fading channel environments. MIMO transmission systems are inv...
متن کاملA Random Matrix Model for $\kappa$-$\mu$ Shadowed Fading
This paper shows that the proposed Rician shadowed model for multi-antenna communications allows for the unification of a wide set of models, both for multiple-input multiple output (MIMO) and single-input single output (SISO) communications. The MIMO Rayleigh and MIMO Rician can be deduced from the MIMO Rician shadowed, and so their SISO counterparts. Other SISO models, besides the Rician shad...
متن کاملImpact of Rician fading and cross-polarization ratio on the orthogonality of dual- polarized wireless channels
The paper examines the impact of Rician fading on the orthogonality of dual-polarized MIMO channels in a measured urban macrocellular scenario. The measurements confirm the previous finding that the Rician K-factors of the crosspolarized channels are strongly correlated to those of the copolarized channels. However, the Rician K-factors do not in general give direct indications on the orthogona...
متن کاملAn Opportunistic-Non Orthogonal Multiple Access based Cooperative Relaying system over Rician Fading Channels
The achievable rate of an opportunistic nonorthogonal multiple access (O-NOMA) based cooperative relaying system (CRS) with channel state information (CSI) available at the transmitter end is analyzed under Rician fading channels. O-NOMA-based CRS achieves better achievable rate than CNOMA-based CRS and results are verified through Monte Carlo simulations. Keywords—Non-orthogonal Multiple Acces...
متن کاملMGF Based Approximate SER Calculation of SMMIMO Systems Over Generalized g 2 l and j 2 l Fading Channels
Spatial modulation (SM) is a multiple input multiple output (MIMO) wireless communication system that gives better spectral efficiency without costing extra bandwith for the same signal constellation size. In an SM MIMO system with Nt transmitting antennas, spectral efficiency increases by log2ðNtÞ. The superior performance of SM systems over other MIMO systems like Alamouti Space-Time Block Co...
