APPARATUS AND METHOD FOR ESTIMATING CHANNEL BASED ON WEATHER DATA
First Claim
Patent Images
1. 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;
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.

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.
