摘要
本文分析了磁光存储系统产生误码的原因，针对系统在读取数据“１”和“０”时信道噪声强度不同这一特殊性，导出了描述信道误码特性的数学模型，并在此基础上研究了磁光信号检偏方式与信道误码特性的关系，分析结果表明：平衡差分信道的容错能力略高于非平衡差分信道。
An analysis of the causes of bit errors is given for magneto-optical storage systems. For the specificity of different noise intensity in the channel when data of one and zero are read respectively,the bit error characteristics in the channel are modeled. Also, this paper deals with an analysis of the relationship of signal detection method and bit error characteristics in channels. It is shown that the fault freedom in balanced differential channels is better than that in unbalanced differential channels.
