Quasi-cyclic low density parity check (LDPC) codes for dedicated short range communication (DSRC) systems
Najmeh Khosroshahi, Thomas Aaron Gulliver · 2010
In this paper, we consider the performance of a dedicated short range communication (DSRC) system for inter-vehicle communications (IVC). The DSRC standard employs convo-lutional codes for forward error correction (FEC). The performance of the DSRC system is evaluated in three different channels with convolutional codes, regular low density parity check (LDPC) codes and quasi-cyclic (QC) LDPC codes. The effects of interleaving are considered. In addition, we compare the complexity of these codes. It is shown that LDPC and QC-LDPC codes provide a significant improvement in performance compared to convolutional codes.
