Abstract
A method, apparatus and decoder for decoding cyclic code are proposed. The decoding method comprises: receiving a transmitted cyclic code; calculating the initial syndrome of the cyclic code; by using the initial syndrome and w prestored successive shift operators, calculating respectively w successive shift syndromes in a w-bit window of the cyclic code in parallel; and detecting/locating error in the cyclic code based on the obtained syndromes. The decoding apparatus corresponds to the above method. And the corresponding decoder is also proposed in this invention. The method, apparatus and decoder according to the invention could process the cyclic code within a window width and thus enhance decoding efficiency in parallel.
