Patent ID: 8787263

Claim:
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.
