Title:
SYNDROME CALCULATION METHOD AND CALCULATION CIRCUIT SUPPORTING CODEWORD SYNCHRONIZATION, AND APPARATUS, DEVICE AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/066066
Kind Code:
A1
Abstract:
A syndrome calculation method supporting codeword synchronization and a corresponding circuit. The method comprises: receiving (N,K)RS codewords, and storing same in a data register, wherein each (N,K)RS codeword is divided into n data blocks, and the data bit width of each data block is (I); by taking 0bit of a first data block of one of the (N,K)RS codewords as a starting position and taking (II) of an nth data block of one of the (N,K)RS codewords as an ending position, acquiring a first group of syndromes; and performing iteration processing on the data blocks and the first group of syndromes, so as to acquire n groups of syndromes corresponding to the two (N,K)RS codewords, wherein N is the length of an RS codeword, K is an information length in the RS codeword, and m is a code element rate. The method significantly increases the speed of searching for an initial position, increases the calculation speed, and saves on logical units and storage space. In the corresponding circuit, a syndrome calculation module function is added, and codeword synchronization is supported.
