Title:
DATA PRE-CODER, SYSTEM AND CODING METHOD
Document Type and Number:
WIPO Patent Application WO/2016/131413
Kind Code:
A1
Abstract:
Disclosed in the present invention is a data pre-coder for performing serial-to-parallel conversion on an inputted serial data stream on the basis of a reference clock, outputting the converted parallel data stream, and generating a data recovery clock; performing the parallel-to-serial conversion on the coded parallel data stream read out by buffer, and outputting the serial data stream; synchronously XOR coding the converted parallel data stream based on the data recovery clock, and outputting the coded parallel data stream; writing the coded parallel data stream into the buffer based on the data recovery clock; and reading out, based on the data transmission clock, the coded parallel data stream which is buffered, and transmitting the coded parallel data stream which is read out to the serial-to-parallel and parallel-to-serial converter for being processed. With said pre-coding method, the coding and decoding of high-speed data stream is simpler, and data code rate in the transmission process is very low thus significantly enhancing the performance of high-speed transmission system.
