Abstract: This application provides a codeword synchronization method, a communication device, a chip, and a chip system, and pertains to the field of communication technologies. The method includes: entering a synchronization position determining state in response to a start signal; determining a synchronization position in a received data sequence in the synchronization position determining state, where the synchronization position indicates a start position of a codeword in the data sequence; entering a loss-of-lock detection state in response to determining the synchronization position; and verifying, in the loss-of-lock detection state, a plurality of codewords selected based on the synchronization position, and re-entering the synchronization position determining state in response to a verification failure. According to the solutions of this application, codeword synchronization can be continuously implemented without inserting an additional alignment marker, thereby saving transmission resources.

Abstract: This application discloses a data transmission method, apparatus, device, and system. The data transmission method includes: A first module obtains at least one channel of first data encoded based on first FEC; converts the at least one channel of first data to obtain at least one channel of second data, where a sum of rates of the at least one channel of second data is not less than a sum of rates of the at least one channel of first data; and transmits the obtained at least one channel of second data. In the method, the at least one channel of first data is converted to obtain the at least one channel of second data whose sum of rates is not less than the sum of rates of the at least one channel of first data.
