Implementation of Multi Bit Error Detection and Correction using Low Density Parity Check Codes

Data transmission in advanced space communications are suffering with the different types of noises. Further, these noises cause burst errors in data. Thus, the low-density parity checking codes (LDPC) plays the major role to detect and correct the errors. However, the conventional hamming encoders, decoders were detected and corrected only one bit error. Therefore, this work implementation the Multi-Bit Error Detection and Correction Codes (MBE-DCC) for multiple bits error detection and correction. Initially, MBE-DCC encoding operation is implemented by using generator matrix, which contains both identity bits and parity bits. Then, encoded code word is transmitted into the channel of space communication, where encoded data corrupted by different types of noises, errors. Therefore, the MBE-DCC decoding operation performed at receiver side of space communications, which corrected all the errors using syndrome detection, error location detection, and error correction modules. The simulations revealed that the proposed MBE-DCC resulted in superior performance than conventional LDPC methods.
