Abstract

This paper investigates the decoding performance of channel-coded ship-based satellite communications on-the-move (SSCOTM) between ships and satellites. In practical communications, ship antennas deviated from satellites by wind waves suffer rapid channel degradation with serious burst errors and even losing all the data. To address this issue, we first establish a mathematical model to study the influence of wind waves and derive the effective signal-to-noise ratio (SNR) in SSCOTM. Second, we propose a vertical Reed-Solomon (RS) with cyclic redundancy check (CRC) and low-density parity check (VRC-LDPC) code, where the RS code and LDPC code are treated as the inner code and outer code to correct both burst and random errors, respectively. Moreover, both the encoder and the decoder of the proposed VRC-LDPC can be carried out in parallel implementations. Finally, simulation results show that the proposed VRC-LDPC performs much better than the conventional codes of the Consultative Committee for Space Data Systems (CCSDS) standard. Thus, this paper provides an excellent alternative channel code for reliable error-correction systems of SSCOTM.
