Solar scintillation effects can be significant for deep-space telecommunication links during superior solar conjunction. In this paper, we propose to apply low-density parity-check (LDPC) codes in the Rician Channel characterized by ionospheric scintillation to improve the BER performance. Simulation results reveal that the coding gain with LDPC codes at 8.4 GHz (X-band) and 32 GHz (Ka-band) are better than convolutional codes, with more than 3.2 db and 2.5 db respectively, and the performance degradation of convolutional codes is deeply affected by channel fading, while LDPC codes represents an excellent performance of channel fading resistance.
