Abstract
Joint design of non-binary Low Density Parity Check (LDPC) code and Hybrid Automatic Repeat Quest (HARQ) is presented for potential application in future satellite tactical data link system. The and performance comparison is evaluated with binary LDPC coded HARQ scheme in term of frame error rate and throughput. Link level simulation results using C + + show that non-binary LDPC code can be integrated into HARQ protocol successful with significant performance gain, especially for chase combining and partial incremental redundancy schemes. Furthermore, non-binary LDPC coded HARQ outperforms the binary one substantially with reasonable complexity increase.
