摘要

通常使用5m作为内存m卷积码截断深度的经验法则，仅对速率为1/2的码是准确的，对于速率为r的码，应该用2到3倍m/(1-r)代替。

A truncation depth rule of thumb for convolutional codes

The commonly used rule of thumb of 5 m for the truncation depth of a memory m convolutional code is accurate only for rate 1/2 codes and should be replaced by two to three times m/(1-r) for a rate r code.
