Time series predictor of Ku band rain attenuation over an Earth-space path at a tropical location

A channel model is proposed to predict the time series of Ku-band rain attenuation during rain events at a tropical location. The model is based on considering the Gaussian distribution of the conditional occurrence of rain attenuation with a particular value of the attenuation occurring before. The mean and standard deviation for the distribution are modelled with the experimental data. The attenuation at a particular time instant is predicted from the measured values at earlier instants. The channel model has tested well giving predicted attenuations which agree with the measured values above 2 dB with a mean error within 10%.
