Abstract

The disclosure provides a method and device for verifying the validity of a codeword, a decoding method and a decoder. According to the present disclosure, a method for verifying the validity of a codeword may include: determining a sum of path metric differences for all nodes in a surviving path of an input codeword; determining a signal quality indicator corresponding to the input codeword; and Based on the sum of the path metric differences and the signal quality indicator, the validity of a codeword decoded from the input codeword is determined. According to the present disclosure, both the sum of path metric differences and the signal quality index are used to determine the validity of a codeword, which can not only eliminate the influence of signal fluctuations, but also achieve better verification performance.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 635,695, filed April 19, 2012, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The embodiments of the present disclosure relate to the field of communication technologies, and in particular, to a method and device for verifying the validity of codewords in Viterbi (viterbi) decoding, and a decoding method and a decoder. Background technique [0004] The continuous growth of mobile data services and the emergence of various new applications have driven the Third Generation Partnership Project (3GPP) to develop the Long Term Evolution (LTE) technical specification. 3GPP LTE is an evolution standard of the hugely successful Global System for Mobile Communications / High Speed ​​Packet Access (GSM / HSPA) technology, which aims to create a series of new standards for new evolved radio access technologies...
