1. Viterbi algorithm is the most likelihood decode algorithm of convolution code. ά�ر������㷨�Ǿ�������������Ȼ�����㷨��
2. Of course, security and encryption also come into play, since the proxy must be able to open the "package" to look at it or decode its contents. ��Ȼ�����ڴ����������������������������ڲ����߶������ݽ������룬����ȫ�ͼ���Ҳ��֮������
3. In order to implement real-time correction of distortion, encoder must encode the digital signals synchronously when decoder begins to decode the analog signals. Ϊ��ʵ�ֻ����ʵʱУ����Ҫ���������ģ���źŽ�����������������źű������ͬ�����С�
