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 individu...
