Embodiment Construction

[0062] 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.

[0063] 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

An embodiment of the present invention provides a decoding processing method and a decoder, the method comprising: receiving the log-likelihood ratio sequence sent by the decoding demodulator; performing pre-decoding on the log-likelihood ratio sequence to obtain At least two sequences of posterior probability log-likelihood ratios; decoding the at least two sequences of posterior probability log-likelihood ratios to obtain a decoding result, the decoding processing method and decoding method provided by the embodiments of the present invention device, which can improve the performance gain of decoding.

Description

technical field [0001] The present invention relates to decoding technology, 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] The turbo code decoder commonly used in the prior art is composed of two identical soft-input and soft-output component decoders, an interleaver and a corresponding deinterleaver. The soft output information of one component decoder is us...
