Abstract: |
The sky wave propagation channel of the high frequency (HF) communicat
ion is suitable for the techniques of Multiple Input Multiple Output (MIMO) beca
use of its rich scattering characteristics induced by the multipath and multi
m
ode propagation phenomena. A survey on the MIMO techniques within the HF band is
given. The feasibility of HF MIMO and the applications in HF MIMO of spaced hom
ogeneous antenna arrays and collocated heterogeneous antenna arrays are highligh
ted. The directions of the future work are also investigated. |
