Study and Performance Analysis of Orthogonal Frequency Division Multiplexing with Different Modulation for Rayleigh Channel Model
Abstract: AbstractFor the advancement of wireless communication systems, methods such as MIMO, OFDM and integrating them together as MIMO-OFDM are very useful. OFDM is used in numerous wireless transmission standards nowadays. In OFDM, high rate data stream is divided into low-rate streams which are transmitted together over a number of subcarriers. A broadband and frequency-selective channel are transformed into a multiplicity of parallel narrow-band single channels by the OFDM modulation. By …

The Onset of Rayleigh-Bénard-Marangoni Convection in a Ferromagnetic Fluid Layer
Abstract: This study examined the implications of magnetic boundary conditions, which are vertical in nature, on buoyancy and surface tension–driven ferrothermal convection (FTC) in a ferrofluid layer. While the upper surface is stress-free and susceptible to general thermal boundary issues, the bottom surface is stiff and insulating against temperature changes. The eigenvalue issue is solved analytically using the regular perturbation method and numerically using the Galerkin technique. According to analysis, raising …
