Embodiment Construction

[0062] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0063] In a communication system, due to the influence of factors such as channel and noise, errors 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 ...

Abstract

The embodiment of the invention provides a decoding processing method and a decoder. The method includes the steps of receiving a log-likelihood ratio sequence sent by a decoding modulator, conducting pre-decoding on the log-likelihood ratio sequence to obtain at least two posterior probability log-likelihood ratio sequences, and conducting decoding on the posterior probability log-likelihood ratio sequences to obtain decoding results. The decoding processing method and the decoder can improve the performance gain of decoding.

Description

technical field [0001] The present invention relates to decoding technology, and in particular, to a decoding processing method and a decoder. Background technique [0002] In modern communication systems, in order to ensure 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 have been placed on error-correcting code technology. Turbo code realizes the content of the stage from channel coding to channel decoding in the communication system, and its bit error rate plays a decisive role in the entire system. [0003] A commonly used Turbo code decoder in the prior art consists of two identical soft-input soft-output component decoders, an interleaver and a corresponding deinterleaver. The soft output information of one component decoder is ...
