卷积码工作或符号流,任意长度。一般来说,他们与维特比解码算法。同时增加约束卷积码的长度,它允许渐近最优译码效率,它仍然是成倍增加的复杂性为代价的。[2]它编码k位信息转化为n位符号。因为k和n很小,很容易传播。与分组码不同,n位代码工作不仅依赖于k位日期,还取决于符号。卷积编码被用于许多应用,如数字视频、广播、移动通信和卫星通信。它是高速和高效。

Convolution codes work on bit or symbol streams, which have arbitrary length. In general, they are decoded with the Viterbi algorithm. While increasing constraint length of the convolution code, it allows asymptotically optimal decoding efficiency, it’s still at the expense of exponentially increasing complexity. [2] It encodes k bits information into n bits symbols. Because k and n is small, it is easy to transmission. Different from Block code, the n bits code work not only depend on the k bits date, but also depend on the forward symbols. Convolution codes are used in numerous applications such as digital video, radio, mobile communication, and satellite communication. It is high speed and efficient.
