摘要

1. The technical field to which the invention described in the claims belongs;The present invention relates to a convolutional coding and decoding method for error detection codes.;2. Technical challenges to be solved by the invention;The present invention improves the decoding speed by determining whether an error is caused by performing a cyclic redundancy check (CRC) of a convolutional-coded error-correcting code before completely decoding all the convolutionally encoded cyclic redundancy check (CRC) bits, A convolutional coding and decoding method of an error-detecting code which improves the transmission efficiency by omitting a process of adding tail bits to the end of the error-detecting codeword and skipping the transmission of the tail bits in the convolutional coding process, The purpose is to provide.;3. The point of the solution of the invention;The present invention includes a first step of convolutionally encoding an error detection codeword without adding tail bits and transmitting the convolutional code; A second step of determining whether an error is detected during the decoding of the convolutionally encoded error detection code; And a third step of delivering the decrypted message until the time when the error detection is determined.;4. Important Uses of the Invention;The present invention is applied to a convolutional encoder and a convolutional decoder.
