Application of non-binary LDPC codes for small packet transmission in vehicle communications

Résumé

We propose to use non-binary low density parity check (LDPC) codes for small packet transmissions in vehicle communications. Non-binary LDPC codes which are defined by a parity check matrix over non-binary Galois field GF(q) can achieve performance very close to the Shannon limit even if they are applied to small block length. By using computer simulations, we demonstrate that non-binary LDPC codes of short block length (896 bits) outperform that of binary LDPC codes and the performance can approach the Shannon limit of this block length by 0.3dB (BPSK) and less than 1.0dB (8PSK, 16QAM) at block error rate = 10 -4 .
