Summary: | Bit-flip caused by SEUs is one of the main reasons resulting in small satellites malfunction. This paper proposes a LDPC erasure decoding method aided by CRC to detect and correct errors in stored data. The key idea is that the encoded message is divided into multiple fragments protected by individual CRC so that fragments with error could be detected and corrected. Moreover, CRC is also used as an early stop criterion of decoding. Simulation and implementation results show that the proposed method has better performance compared with MS decoding both in error correcting and hardware requirements. |
