维特比译码非常经典，每个通信从业人员对其译码算法都应该十分了解。本例程在具体实现事，充分考虑软件译码的时效性能，采用译码深度自适应的方式对传统VIT译码进行改进，译码效果提高非常明显。(Vitby decoding is very classic, each communication practitioners on their decoding algorithm should be very understanding. This routine in concrete implementation, take full account of the timeliness of software decoding performance, the use of decoding depth adaptive way to improve the traditional VIT decoding, decoding effect is very obvious)
