摘要： A method for sending uplink burst data in a passive optical network (PON) system includes: sending a synchronization pattern of the uplink burst data, the synchronization pattern being of a length, which is an integer multiple of 66 bits, and being formed by connection of 66-bit unit gene blocks; sending a burst delimiter (BD) of the uplink burst data; sending a forward error correction (FEC)-protected data in the uplink burst data; and sending an end of burst (EOB) delimiter of the uplink burst data. The technical solutions in the embodiments allow the use of a less complex equalizer at the reception end of a high-speed PON system.

摘要： The present invention relates to the communication field, and discloses a method and an apparatus for encoding, decoding, receiving and transmitting data to improve the encoding gain of the FEC encoding without increasing transmission overhead. In the present invention, no FEC encoding is performed for the minor bits in the block header of the information blocks. The block header may be a sync header. The bit indicative of the data type serves as a major bit, and is protected through FEC encoding; the bit for the only purpose of block synchronization serves as a minor bit, which is not involved in the FEC encoding and decoding. When the buffered data are deficient, padding blocks are padded into the buffer to trigger the FEC encoding in time; after the FEC encoding, the padding block is removed from the encoding result, thus avoiding transmission of unnecessary data.
