Abstract
This application relates to the communications field, and discloses an encoding method, a decoding method, an encoding apparatus, and a decoding apparatus. The encoding method includes: receiving a data bitstream; performing forward error correction FEC encoding on the data bitstream to obtain X Reed-Solomon RS outer codes, where each of the X RS outer codes includes N1 symbols, K1 of the N1 symbols are payload symbols; and performing FEC encoding on the X RS outer codes to obtain Y RS inner codes, where each of the Y RS inner codes includes N2 symbols, K2 of the N2 symbols are payload symbols. According to this application, error correction performance of FEC decoding can be improved.
