The purpose of this research is twofold. One is to analyze the noise threshold of the regular LDPC codes with a BPSK system on an LEO satellite channel. Through analysis of noise threshold, we can determine minimum SNR to achieve the best performance of regular LDPC codes among different code rates and degree parameters. The other is to analyze the effect of fading parameters of the LEO satellite channel on the performance of regular LDPC codes. For this, we investigate the probability density function of a fading factor depending on the parameter values of the Loos model and analyze the performance of regular LDPC codes. Numerical analysis and simulation results are shown with discussions.
