And a decoder decoding processing method

Embodiments provide a decoding method and a decoder according to the present invention, the method comprising: obtaining Gturbo Turbo code generation matrix generates the CRC for the combined generation matrix matrix Gcrc Gcom, and acquires Turbo code decoder output the log-likelihood ratio sequence; employing the iterative joint generating ordered statistics decoding and Turbo code matrix Gcom the log-likelihood ratio sequence, the CRC assisted, the decoding processing result is obtained. Turbo decoding method and apparatus provided by the embodiments of the present invention can improve the decoding performance gains.
