Title:
A METHOD AND DEVICE FOR ENCODING DATA AND DECODING DATA
Document Type and Number:
WIPO Patent Application WO/2009/067899
Kind Code:
A1
Abstract:
A method for encoding data includes the following steps: after line-coding and FEC encoding, the synchronization head is added into the encoded data, the frames are generated based on the encoded data and are transmitted. The device for encoding data, the method and the device for decoding data are disclosed at the same time. Because the redundant information which is used for synchronizing is added into the encoded data, the synchronization performance of transmission system can be ensured even when the degree of redundancy of the selected algorithm is small. Because the extra added synchronization head is not used in the FEC encoding, the encoding gain can not be influenced.
