Abstract
In a satellite communication system, a central station receives a message including channel measurement information that is provided from a terminal and calculates a channel estimating value based on the received channel measurement information and weather data of a region corresponding to a location of the terminal. The central station determines encoding and modulation methods of data to transmit based on the calculated channel estimating value.
Claims14
A method of estimating a channel, the method comprising:
- receiving, by a central station, a message comprising channel measurement information from a terminal;
- extracting, by the central station, channel measurement information from the received message and acquiring sample data by processing the channel measurement information;
- acquiring, by the central station, weather data corresponding to a region at which the terminal is located, wherein the acquiring of sample data comprises:
- providing a first weight value to previously calculated sample data and applying a different weight value from the first weight value to present channel measurement information that is extracted from the received message;
- and
- calculating sample data of the received message based on the previous sample data to which the first weight value is applied and present channel measurement information to which a different weight value from the first weight value is applied;
- calculating, by the central station, a channel estimating value based on the sample data and the weather data;
- and
- determining, by the central station, encoding and modulation methods for processing data based on the channel estimating value.
