Embodiment Construction

[0063] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0064] 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 normal data. The decoding processing method in the embodiment of the present invention can be applied to the decodi...

Abstract

Embodiments of the present invention provide a decoding processing method and a decoder. The method includes: acquiring a joint generator matrix Gcom of a turbo code generator matrix Gturbo and a cyclic redundancy check CRC generator matrix Gcrc, and acquiring the output of the turbo code decoder The log-likelihood ratio sequence of CRC; using the joint generator matrix Gcom and the log-likelihood ratio sequence, perform CRC-assisted iterative sorting and statistical decoding of the turbo code, and obtain the decoding processing result. The Turbo code decoding method and device provided by the embodiments of the present invention can improve the decoding performance gain.

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. Especially with the development of wireless digital communication and the emergence of various high-speed and bursty services, higher and higher requirements are put forward for error-correcting code technology. The Turbo code realizes the content from channel coding to channel decoding in the communication system, and its bit error rate plays a decisive role in the whole system. [0003] Turbo code is a forward error correction channel coding and decoding technology. Its encoder is composed of two recursive circular convolutional codes combined in a parallel cascaded manner through an interleaver, ...
