摘要
Morse码自动译码方法,使用锁相环锁定Morse码频率,然后通过译码处理器捕捉Morse码并计算点码、划码及码间隔的时长,从而根据点码与划码的组合自动译出字符并显示到终端。该译码算法步骤包括定义译码窗口与字符析出、编制Morse码字符表。软件编制分为高低电平时长的计算程序和字符析出程序两个主要部分。
The automatic decoding method locks the frequency of Morse code by phase locked logic circuit at first. Then it captures the long code, short code and time distance between codes by decoding processor, so Morse code is decoded to character and shown to terminal according to combination of long code and short code. The algorithm of decoding includes defining the coding window, separating the character and working out the Morse code character table. The software includes computing program defined by high and low voltage and program of separating the character.
