将多径编码方法引入网间互联技术，提出一种新的信源编码转换方法，实现了在无信道传输误码的影响下多次转接无误差积累。设计实现了１６ｋｂｐｓＣＶＳＤ与３２ｋｂｐｓＣＶＳＤ全数字多径转换算法，模拟结果表明，该算法是正确、有效和可行的。这一方法的提出，保证了网间互联信源编码转换质量，提高了信息利用率及延伸了信息传输距离，对我国通信网建设有重要意义。
The multi-path coding method is introduced into the internetworking technology, a new source coding method is proposed, which achieves error-free accumulation of multiple handovers without channel transmission errors. The 16kbps CVSD and 32kbps CVSD full digital multipath conversion algorithms are designed and implemented. The simulation results show that the algorithm is correct, effective and feasible. This method is proposed to ensure the quality of transcoding of source code of internetworking, improve information utilization and extend the information transmission distance, which is of great significance to the construction of China’s communication network.
