A novel comparative study of different low‐density parity‐check (LDPC) coding algorithms and implementation issues through field‐programmable gate arrays (FPGAs) technology for wireless vehicular applications is presented. A key development in LDPC codes is the iterative decoding algorithm which uses the belief propagation algorithm. A comprehensive investigation of the performance of different coding schemes was carried out. Four different decoding techniques were tested by computer‐based simulations of messages modulated under the binary phase‐shift keying modulation scheme and transmitted through a vehicular channel model. Finally, the best performance ratio against complexity algorithm was chosen to be implemented on a Xilinx FPGA platform.
