Abstract
Embodiments of the present invention provide a method and a decoder for processing decoding. The method includes: acquiring a combined generator matrix Gcom of a Turbo code generator matrix Gturbo and a cyclic redundancy check CRC generator matrix Gcrc, and acquiring a log likelihood ratio sequence outputted by a Turbo code decoder; and performing CRC-assisted iterative ordered statistics decoding of a Turbo code by using the combined generator matrix Gcom and the log likelihood ratio sequence, so as to obtain a decoding processing result. A decoding performance gain can be improved by using the method and the device for decoding a Turbo code provided in the embodiments of the present invention.
