Error rate prediction of the low Earth orbit (LEO) satellite channel

Error rate prediction the LEO land mobile satellite channel is presented. Since it could hardly be expressed the error rate under the practical degradation factors in a closed form, the method to predict the error rate using the known moments of the degradation factors is employed. The numerical result in this analysis especially under the effects of the traveling wave tube amplifier (TWTA) nonlinearity, fading effect and intersymbol interference (ISI) is provided. Using the Rician fading channel model with the parameter K used to describe the elevation angle dependent fading factor, in the LEO environment, the result shows that the system performance is poor when the LEO satellite is located at a lower elevation angle (EL)
