This paper presents the simulated capacity results that could be achieved when echelon, H-shaped, V -shaped free standing dipoles and printed dipole arrays are used in the MIMO systems. As the configurations of interest, in this paper, have dipoles oriented in different directions, the channel model for multi-polarized antennas is used in the simulations. The polarization change at every scatterer...
In mobile communication environment, the wireless channel is time varying due to the mobility of the wireless terminal and multi-path propagation. It has been shown that MIMO will give multiplexing gain and/or better quality of service. It has also been proved that AAS can provide improved spectral efficiency because AAS uses spatial multiplexing technique. This paper proposes an algorithm for reconfigurable...
With the rapid growth of digital communication in recent years, the need for high speed data transmission is increased. OFDM is a promising solution for achieving high data rates in mobile environment, due to its resistance to ISI, which is a common problem found in high speed data communication. A multiple-input multiple-output (MIMO) communication System combined with the orthogonal frequency division...
