摘要：By using MATLAB, a kind of software decoder is designed which has filter and fault correction function and is used in aviation radio communication. Through Morse code text, using dits and dashes to uniquely represent characters such as alphabets 、 numbers and punctuations (41), those characters are coded through algorithm. A new decoding algorithm is designed which is composed of filtration, binary, difference and zero removal operation. This decoding method is robust and interference immunity, it also has such functions as filtering and fault correction. It can filter the random noise and Gaussian noise so as to reduce the error rate of aviation radio communication and thereby increase the quality of aviation radio communication. This method is checked though an example to decode the word "Hello".
