在简述数字存储原理的基础上给出基本存储信道各种模型及其容量上下限。分析了两种检测技术 (峰值检测与部分响应最大似然Viterbi检测 )的优缺点 ,采用受限码的原因及其基本编译码器构成。
Based on the brief description of the principle of digital storage, various models and their upper and lower limits of the basic storage channel are given. The advantages and disadvantages of two detection techniques (Peak Detection and Partial Response Maximum Likelihood Viterbi Detection) are analyzed. The reason of using restricted codes and their basic codecs are analyzed.
