    Abstract
  • An efficient dynamic resource calculation algorithm applicable to satellite networks was presented. The rain attenuation was taken into account, and adaptive forward error correction(FEC) coding technology was used to mitigate the decrease in signal to noise ratio caused by rain. In order to guarantee the information date rate and bit error rate, the proposed scheme adaptively increases the number of channels to transmit more information date.The algorithm-s performance was validated through simulation of different rain rates and frequencies, and the theoretical analysis and simulation results were matched perfectly.
