MH及MR码的新型快速解码方法的设计与实现

改进的霍夫曼码（MHC）及改进的相对地址码（MREAD Code)是三类传真机信源编码的标准。本文讨论一种新的解码方案，即将码表重新分类组合，不需传统解码方法的译码树而在计算机上实现快速解码，显示在计算机上，结合已经做好的传真信息接收卡，可以监测电话线路上收，发的传真。

Fast Decoding of Modified Huffman Code and Modified Reference Address Code and Its Realizatin

Modified Huffman Code (MHC) and Modified Reference Address Code (MRC) are Standards of Generation 3 Fax Information Source Coding.This paper introduces a new method of decoding MHC and MRC by re-classifying the code tables.Displaying the decoded fax information on the computer screen,this method works faster than traditional ones without any cecode tree of the latter.Combined with a fax receiving card,it can be used to supervise faxes sent of rceived on the telephone line.
