Problems solved by technology

[0007] Therefore, the receiving apparatus having the initial decoding method has a disadvantage that, in a stacked state, an error occurs even if the decoding process is repeated many times, and the invalid decoding process is repeatedly performed irrespective of the inability to decode the information.

Embodiment approach

[0032] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In this embodiment, a communication system includes a transmitting device and a receiving device. Here, the reception device of the communication system receives a transmission signal including information that has been error-corrected encoded by the transmission device, and decodes the information by repeating decoding processing. In addition, in this embodiment, the above-mentioned error correction code is a Turbo code, and the coding rate of this Turbo code is 1 / 2.

[0033] figure 1 It is a schematic block diagram showing the configuration of the transmitting device. The transmitting device includes an encoding device 1 , a wireless transmitting unit 2 and a transmitting antenna 3 .

[0034] The coding device 1 includes an interleaver 11 , a first RSC (Recursive Systematic Convolutional: feedback system convolution) coding unit 12 , a second RSC coding uni...

Abstract

Provided is a decoding device which repeats a decoding process so as to decode information which has been subjected to an error correction encoding. The device includes a repetition quantity decision unit which calculates mutual information amounts of the encoded information and decides a repetition quantity of the decoding process according to the calculated mutual information amounts.

Description

technical field [0001] The present invention relates to a decoding device, a decoding method, a decoding program, a receiving device, and a communication system. [0002] this application claims priority based on Japanese Patent Application No. 2008-033252 for which it applied to Japan on February 14, 2008, and uses the content here. Background technique [0003] In recent years, when transmitting information from a transmitting device to a receiving device in a wireless communication system, the transmission device adopts pre-alignment error (bit error, ビツト传り) corrected error correction code is the premise. In particular, the turbo code discovered in 1993 as an error-correcting code with a high error-correcting capability is introduced into various current wireless communication systems as a code that is completed close to the theoretical limit in a communication system. The turbo code has two identical code parts arranged side by side on the transmission side, and rearra...
