Abstract

The invention discloses a Turbo code word generation method and decoding method. The Turbo code word generation method comprises the steps of allowing at least two secondary coders coding and decodingsimultaneously to receive a code input sequence, wherein the code input sequence at least comprises a symbol comprising at least two information bits; and coding the received code input sequence by using an RSC through at least two secondary coders, and generating and outputting a coding result. The Turbo code word decoding method comprises the steps of receiving an input to-be-decoded sequence;and decoding the to-be-decoded sequence through a decoder, so as to obtain and output a decoding result, wherein the decoding process comprises a first decoding stage and a second decoding stage, wherein in the first decoding stage, a first decoding device RSCDEC decodes the RSC, and in the second decoding stage, a second decoding device PCRCDEC performs PCRC decoding on a decoding result of the first decoding stage. In related technologies, low code rate Turbo code is complicate to code and decode. The invention solves the technical problem in the related technologies.

Description

technical field [0001] The present invention relates to the field of information processing, in particular, to a generation method and a decoding method of a Turbo code word. Background technique [0002] At present, the idea of ​​iterative decoding of Turbo codes has been hailed as "Turbo Principle". Applications. In terms of practical application, although in a period of time after the appearance of Turbo codes, due to the complexity and decoding delay of Turbo codes, its practical application is limited. However, after more than ten years of research, both the encoding scheme and the decoding algorithm of Turbo codes have been quite mature. Now Turbo codes have officially entered the mainstream stage and become the real darling of the times. Turbo codes are adopted in various communication standards. as one of its standards. In the field of deep space communication, the 16-state Turbo code is listed as a new standard by the Space Data Standards Consultative Committee (...
