计算机集散系统中通信差错控制的研究

A Study on Communication Error Control in the Distributed Computer System

为了在恶劣环境中提高计算机数据通讯的实用性和正确性,提出了采用纠1检2的扩展海明码以及分组交错收发的数据处理方法,用以抑制随机差错和突发差错,使信道的等效误码率下降两个数量级,对提高计算机通信的实际能力有很好的效果.

An expanded Hamming code capable of correcting 1 and detecting 2 bits and a data processing approach of block transposed transmitting -receiving are proposed to enhance the real-time property and correctness of computer data communication. The application of the code and approach in suppressing random errors and burst errors makes the equivalent error rate drop by 2 orders of magnitude and proves highly effective in improving the actual performance of computer communication.
