Low density parity check (LDPC) codes have the ability to transmit data at rates approaching channel capacity with very low error probability. Our study of LDPC codes on JPEG2000-compressed ultraspectral sounder data shows that for an LDPC encoder designed with certain input parameters, the LDPC decoder is able to correct all single errors and two-bit burst errors. Furthermore, our analysis on a massive variety of 3- and 4-bit burst error scenarios indicates that the locations of LDPC-uncorrected errors for 3- and 4-bit burst errors appear to be fixed, regardless of the content of the input data. We propose a look-up table based error correction method to correct errors surviving from the LDPC decoder for 3- and 4-bit burst errors.
