Abstract: Low-Density Parity-Check codes (LDPC) are found to be efficient at high code rates and have a low error probability and also provide a higher coding gain when compared to other coding techniques working in this domain. This paper proposes a LDPC encoder and also construction of parity check matrices for different code rates, as specified in the CCSDS 131.1-0-2 document [8]. To evaluate the encoder a VHDL description was developed and synthesized on an Altera Cyclone platform for the CCSDS standard.
