In this paper we introduce the satellite communication system which consists of redundant central station with management module to increase the stability of the satellite link. Configuration of redundant central station in satellite communication system can minimize the service interruption due to unstable link or some module error. According to this, we expect to ensure efficient use of technology...
In this paper, we propose a channel estimation method associated with the interpolation order for DVB-T systems. We first analyze the time varying channel and frequency selective channels, and then derive the channel index which indicates the ratio of the time and the frequency axis variation. This channel index is used for determining the order of interpolation such as time axis followed by frequency...
