1. A system comprising:
a first wireless communication node for transmitting a data signal as an electromagnetic wave, wherein the data signal is sent over a first data transmission path and a second data transmission path using skywave propagation;
a second wireless communication node configured to receive and decode the data signal transmitted from the first wireless communication node;
wherein the first data transmission path includes at least one reflection point, wherein the data signal is reflected by the atmosphere;
wherein the second data transmission path includes more reflection points than the first data transmission path;
wherein the second wireless communication node is configured to measure a first arrival angle of the data signal from the first data transmission path;
wherein the second wireless communication node is configured to measure a second arrival angle of the data signal from the second data transmission path;
wherein the second wireless communication node is configured to determine the first data transmission path has fewer hops than the second data transmission path based on the first arrival angle and the second arrival angle; and
wherein the second wireless communication node is configured to decode the data signal received from the first data transmission path before decoding the data signal received from the second data transmission path.
