(1) The repository provides two ways of channel modelling, i.e., the unified channel model (the elemment of which is determined by the BS-UAV antenna pair distance) and the far-field channel model (which is parameterized by AoA/AoD), to illustrate the difference between far-field and near-field wireless channels.
(2) The code can be used in simulations for the MIMO communication link with arbitary Tx/Rx array shapes and orientations.
