Abstract
A wireless communication system includes a first wireless communication node for transmitting a data signal that is sent to a second wireless communication node by skywave propagation over at least two different data transmission paths. The first data transmission path includes at least one reflection point where the data signal is reflected by the atmosphere and the second data transmission path includes more reflection points than the first data transmission path. The data signal that travelled along the first data transmission path is decoded before the data signal that travelled along the second data transmission path.
Claims19
A system comprising:
- a first wireless communication node for transmitting a data signal as an electromagnetic wave, wherein said 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;
- wherein the second wireless communication node is configured to designate a decoding order based on the first data transmission path having fewer hops than the second data transmission path;
- and
- wherein the second wireless communication node is configured to start decoding the data signal from the first data transmission path before the data signal from the second transmission path based on the decoding order.
A method comprising:
- transmitting a data signal from a first wireless communication node, wherein said data signal is sent over a first data transmission path and a second data transmission path using skywave propagation, and wherein said first data transmission path includes at least one reflection point wherein the data signal is reflected by the atmosphere and the second data transmission path includes more reflection points than the first data transmission path;
- receiving the data signal from the first data transmission path and the second data transmission path at a second wireless communication node;
- measuring one or more properties of the data signal from the first data transmission path and the data signal from the second data transmission path with the second wireless communication node;
- wherein the properties include arrival angle;
- determining the first data transmission path has fewer hops than the second data transmission path based on the properties;
- deciding a decoding order based on the determining the first data transmission path has fewer hops with the second wireless communication node;
- wherein the deciding a decoding order includes designating that decoding of the data signal from the first data transmission path starts before decoding of the data signal from the second data transmission path;
- and
- decoding the data signal from the first data transmission path.
