Abstract:
(EN) Disclosed is a decoding device which selectively surrenders, by processing a situation that values of updated code elements exceed a quantization range of the code elements during a code word updating process for LDPC codes, update in the situation that the updated code elements exceed the quantization range of the code elements, thereby preventing the decoding device from directly quantizing the updated code words that exceed the quantization range of the code elements, and improving the error correcting capability of the decoding device during decoding.
(FR) L'invention concerne un dispositif de décodage qui, par le traitement d'une situation dans laquelle des valeurs d'éléments de code mis à jour dépassent une plage de quantification des éléments de code pendant un processus de mise à jour de mot de code pour des codes LDPC, renonce de manière sélective à la mise à jour dans une situation dans laquelle les éléments de code mis à jour dépassent la plage de quantification des éléments de code, empêchant ainsi le dispositif de décodage de quantifier directement les mots de code mis à jour qui dépassent la plage de quantification des éléments de code, et améliorant la capacité de correction d'erreurs du dispositif de décodage pendant le décodage.
(ZH) 本发明实施例公开了一种译码设备,该译码设备通过对LDPC码的码字的更新过程中出现的更新后码元的取值超出码元的量化范围的情况进行处理,有选择的放弃了更新后码元超出码元的量化范围的情况下的更新,避免了译码设备对于超出码元的量化范围的更新后的码字的直接量化,提升了译码设备的译码过程中的纠错能力。
