在编码器复杂度相同的情况下，卷积码的性能优于分组码，因此卷积码几乎被应用在所有无线通信的标准之中，如GSM， IS95和CDMA 2000 的标准中。-Complexity in the encoder the same circumstances, convolutional codes perform better than block codes, the convolutional code is used in almost all wireless communication standards process, such as GSM, IS95 and CDMA 2000 standards.
