Paper Abstract

This paper presents the performance analysis and optimization of LDPC coded OFDM system which provides high signal quality in LEO satellite communications. A three-state statistical channel model of LEO satellite channel is adopted including Rayleigh, Rician and shadowed Rician distributed submodels. The Irregular LDPC codes without loops of length 4 are optimized by the differential evolution algorithm under this LEO satellite channel. Simulations of BPSK, QPSK, 16QAM modulated systems are also conducted to analyze performances of theses systems.
