Abstract—Nowadays, Dedicated Short Range Communication (DSRC) system’s application is increasing fast, and has been applied to electronic toll collection, parking management, traffic control and other fields. Meanwhile, the complexity and quantity of data is also increasing, thus making the implementation and security requirements more strict. Compared with Turbo codes, Low Density Parity Check (LDPC) codes can achieve a better safety and performance, which have been widely studied. Based on this, we try to apply LDPC codes into DSRC system. In this paper, we first introduce the basic content of DRSC standard, and then analyze LDPC codes in DSRC system. At the end, by simulations, we do comparisons between LDPC codes and conventional Turbo codes in DSRC system when using different decoding algorithms and in different channels.
Index Terms—DSRC system, LDPC codes, turbo codes, performance, complexity
