Abstract :
A three dimensional (3-D) cylinder scattering model is proposed for multiple-input multiple-output (MIMO) Land Mobile Stratospheric multipath fading channels. Analytical expressions for the space-time correlation function between two arbitrary sub-channels are derived in non-isotropic environments. This model can be used to estimate the required high altitude platform (HAP) antenna separation to achieve an uncorrelated HAP-MIMO channel matrix. Theoretical derivations have been derived through extensive computer simulations. Our procedure provides an important framework for designing and testing future HAP-MIMO based communication systems and studying the channel capacity of HAP-MIMO based channels, with LOS and NLOS components.
