Combined FDMA-TDMA - A cost effective technique for digital satellite communication networks
Abstract
Satellite transponder channelization is discussed along with the concept of combined FDMA-TDMA. The economic impact of the number of carriers employed in the transponder which may be time shared by a group of earth stations is demonstrated. In particular, it is shown that the lack of transponder TWT back off in fully TDMA system is not as effective in minimizing the network cost as the decrease in the transmitter power in combined FDMA-TDMA operation. It is also emphasized that for low traffic requirements the earth station antenna size of about 4m is the most appropriate.
