Decoding processing method and decoder

Abstract

The embodiment of the invention provides a decoding processing method and a decoder. The method comprises the steps that union generator matrixes G of tail biting convolution code generator matrixes GTBCC and unit matrixes I are obtained, and pre-decoding soft value sequences and hard judgment sequences output by the soft output decoder are obtained; according to the union generator matrixes G, the pre-decoding soft value sequences and the hard judgment sequences, sorting statistics and decoding are carried out on tail biting convolution codes, and decoding processing results are obtained.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a decoding processing method and a decoder. Background technique [0002] In modern communication systems, in order to ensure the reliable and effective transmission of various data in the channel, it is often necessary to use error correction coding technology. As an efficient channel coding, convolutional code not only has excellent bit error performance, but also has the advantages of simple coding and decoding structure and small processing delay. [0003] In the decoding process of the convolutional code, not only the decoding information is extracted from the code group received at that moment, but also the relevant information is extracted by using the code group received in several moments later. Based on this decoding algorithm, the currently more commonly used decoding algorithm is the Viterbi decoding algorithm. The Viterbi algorithm is the maxi...
