    摘要： A service providing method in a satellite communication system includes: receiving service request signals from terminals which exist in a service area and are to receive the communication service; calculating the total traffic volume within the service area by using the service request signals; forming hierarchical multi beams which cover the calculated traffic volume to provide a service to the terminals; and allocating resources and power to the formed hierarchical multi beams, transmitting the resource and power allocation information to the terminals through control channels, and providing the service to the terminals through the formed hierarchical multi beams by using the allocated resources and power.

    摘要： Disclosed herein is a Kalman filter channel estimation method for an OFDM system. The Kalman filter channel estimation method for an OFDM system includes estimating a channel using a least squares based on a reference signal location, calculating Kalman gain for the estimated channel, and updating the estimated channel in accordance with the calculated Kalman gain, wherein the calculating the Kalman gain includes obtaining the Kalman gain using a quasi-Newlon technique.

    摘要： In a system where satellite communication using multi-beams is performed for each group including a plurality of beams, a required data transmission rate of each beam is detected for each group, more traffic resources are allocated to a beam having a higher required data transmission rate than other beams based on the detection result, and data traffic transmitted to each beam in the group is adaptively controlled.
