Embodiment Construction

[0077] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0078] In a communication system, due to the influence of factors such as channel and noise, errors will inevitably occur during data transmission. In order to reduce the bit error rate under the same signal-to-noise ratio, the transmitter needs to use appropriate channel coding, and the receiver needs to perform corresponding decoding to restore ...

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. The method can improve the decoding performance.

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...
