Performance Analysis of SPSK with Dual Polarized Transmit Antennas over Rayleigh Fading Channel

Subramani M., Neduncheran A. V., Ponnusamy V.

Journal of Telecommunications and Information Technology

2018

nr 1

58--61

In this paper, the Space Polarization Shift Keying (SPSK) system, which is an extended version of Space Shift Keying (SSK) and includes both space and polarization dimensions with dual polarized antennas, is studied. The capacity and error probability analysis of SPSK for different polarization configurations are dealt with over the Rayleigh fading channel with a rich scattering environment. The analysis conducted shows that the SPSK with a dual polarized antenna (DP) offers better results than SPSK with a single orthogonal polarized antenna SPSK(SP), under non-LOS conditions. SPSK(DP) outperforms SSK by 4.2 dB over the correlated Rayleigh fading channel at 3 bits/s/Hz.

The stress state analysis of rescue seat area of submarine Kobben class during rescue vehicle landing

Szturomski B., Bohn M.

Journal of Polish CIMAC

2014

Vol. 9, no 3

91--99

Lists the documents that contain guidelines for the preparation of the design model using Finite Elements Methods (FEM) [5], reflect the geometry of the object and its discretization, a description of the material, boundary conditions and loads. Posted examples of the results of the stress state in the design of the seat area of submarine Kobben class rescue obtained from simulation FEM for deep 250m. This article includes calculating stamina of seat area construction (stress states) during rescue vehicle type SRC or DSRV docking taking into account the depth of immersion and sea current in CAE program, which are the basis for determining the maximum safe depth for use the emergency system.
