Der Wiederholungscode ist der einfachste fehlerkorrigierende Kanalcode. Er wiederholt jedes übertragene Symbol -mal. (de) In coding theory, the repetition code is one of the most basic error-correcting codes. In order to transmit a message over a noisy channel that may corrupt the transmission in a few places, the idea of the repetition code is to just repeat the message several times. The hope is that the channel corrupts only a minority of these repetitions. This way the receiver will notice that a transmission error occurred since the received data stream is not the repetition of a single message, and moreover, the receiver can recover the original message by looking at the received message in the data stream that occurs most often. Because of the bad error correcting performance coupled with the low code rate (ratio between useful information symbols and actual transmitted symbols), other error correction codes are preferred in most cases. The chief attraction of the repetition code is the ease of implementation. (en) Le code de répétition est une solution simple pour se prémunir des erreurs de communication dues au bruit dans un canal binaire symétrique. C'est une technique de codage de canal, c'est-à-dire un code correcteur. (fr) 反復符号（英: Repetition code）とは、ビットを反復することで伝送路上の誤りのない通信を実現する 符号化手法である。反復符号は非常に単純な符号化手法である。フェージングのある通信路では反復回数が多いほど誤り率が低下するが、ホワイトノイズが加算されるような通信路では逆に誤り率が高くなる。 (ja) |
