The channel environment of the optical wireless communication is complicated, susceptible to various natural phenomena such as rain, snow, and fog.The channel code is usually used to correct the error caused by the channel noise.Common channel codes are Reed-Solomon (RS) code, Turbo code, low density parity check (LDPC) code, polarization code and other types.The development of the error correction code was combed, the research progress of the error correction code for the optical wireless communication were summarized and the comparative analysis was made, which introduced the progress of Xi'an University of Technology in this field of theory and experimentation.RS code, Turbo code, LDPC code were comparable to the error correction characteristics in rain, snow and fog environments.Finally, the future possible research direction and challenges were pointed out, providing references for the future development and research in the relevant fields.

Key words: optical wireless communication, error correction coding, bit error rate
