Rain attenuation compensation method using adaptive transmission technique and system using the same |
摘要 |
A rain attenuation compensation method that includes estimating a signal-to-noise (S/N) ratio from PSK-modulated receiving signal at a receiving end; predicting a signal-to-noise (S/N) ratio of the next time point on the basis of the signal-to-noise (S/N) ratio values of the past and present time points; and determining which of transmission methods is adequate to the predicted signal-to-noise (S/N) ratio of the next time point. If the switching of the transmission method is determined, a control signal for inquiring the change of the transmission method is transmitted to a transmitting and a receiving end. Data is then transmitted by the switched transmission method.
