In digital transmission, the Viterbi error rate, also known as the Viterbi bit error rate (VBER), is a measurement of error in the transmission of digital Information after the original signal has been corrected for errors and aberrations, usually noise and/or distortion. The value of the VBER is directly linked to the quality of the Channel Bit Error Rate (CBER), a measurement of the strength & quality of the original signal. ==Example== Here is an example of transmitted digital code. 1 0 1 0 1 The following, ''distorted'' signal is received. 1 1 0 1 0 The CBER is determined by dividing the number of incorrectly received digits, or bits, (in this case 4), by the total number of bits received. So, in this case, the CBER is equal to 4/5 which equals 0.8, or 80%. That is, 80% of the bits were incorrectly received. Except for ''extreme'' cases of interference, a signal can be completely corrected and thus achieve a VBER of 0. That is, a signal with 0 post correction errors can be achieved. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Viterbi error rate」の詳細全文を読む スポンサード リンク
