用于位模式化媒体记录的写通道模型
Write Channel Model for Bit-Patterned Media Recording
摘要:
我们提出了一个新的写入通道模型位模式化的媒体记录,反映了数据的写入同步错误的依赖。它示出,该模型容纳替代类错误和插入删除错误,其统计由一个潜在的信道状态过程。研究了写信道模型的信息论性质,包括容量、对称信息率、马尔可夫-1率和零差错容量。
英文摘要:
We propose a new write channel model for bit-patterned media recording that reflects the data dependence of write synchronization errors. It is shown that this model accommodates both substitution-like errors and insertion-deletion errors whose statistics are determined by an underlying channel state process. We study information theoretic properties of the write channel model, including the capacity, symmetric information rate, Markov-1 rate and the zero-error capacity.
