On the error detection capability of combined LDPC and CRC codes for space telecommand transmissions

Marco Baldi, Nicola Maturo, Giacomo Ricciutelli, Franco Chiaraluce
2016 2016 IEEE Symposium on Computers and Communication (ISCC)  
We present a method for estimating the undetected error rate when a cyclic redundancy check (CRC) is performed on the output of the decoder of short low-density parity-check (LDPC) codes.  ...  We show that these new LDPC codes combined with CRC are adequate for complying with the stringent requirements of this kind of transmissions in terms of error detection.  ...  In the rare cases in which p * actually corresponds to the CRC redundancy computed on s * , the error is undetected by the CRC code as well.  ...
