The performance of multiple-input multiple-output MIMO systems strongly depends on the correlation between antenna elements. In this paper, we propose a model for calculating the correlation between multi-polarized Rayleigh fading MIMO channels, which takes into account not only the gain patterns of both transmitting and receiving antennas, but also the polarization matrix of the propagation channel,...
The performance of multiple-input multiple- output (MIMO) systems strongly depends on the correlation between antenna elements. An analytical expression is given for the 3D spatial correlation (SC) coefficient of half-wavelength (??/2) dipole antennas by using spherical mode expansion of plane waves. The mutual coupling (MC) effect is also considered using the concept of coupling matrix. Our results...
We extend the study of Fei (IEEE Transactions on Antennas and Propagation, vol. 56, no. 11, pp. 35663575, Nov. 2008) on single-port matching impedance for capacity maximization in compact 2 ?? 2 multiple-input-multiple-output (MIMO) systems to N ?? N MIMO systems. In addition, we increase the degrees of freedom of the uncoupled matching where each port is terminated by an arbitrary load impedance...
