我们提出了一个多输入多输出（MIMO）扩展的定时误差检测器（TED），最初开发的Mueller和Müller的脉冲幅度调制1-D信道上的同步。该MIMO扩展应用于从二维磁记录（TDMR）信道中的一个或多个读回波形联合检测多个异步磁道。我们提供了准确的理论表达式所提出的方案的性能，并验证其适用于现代MIMO TDMR信道。性能测试结果表明，所提出的TED优于传统的1-D TED，完全忽略了MIMO信道中的串扰干扰的存在。
We present a multiple-input multiple-output (MIMO) extension of the timing error detector (TED) that was originally developed by Mueller and Müller for synchronization on pulse-amplitude modulation over 1-D channels. This MIMO extension applies to the joint detection of multiple asynchronous tracks from one or more readback waveforms in a two-dimensional magnetic recording (TDMR) channel. We provide accurate theoretical expressions of the performance of the proposed scheme and verify its applicability on a modern MIMO TDMR channel. Performance results show that the proposed TED outperforms the conventional 1-D TED that completely ignores the presence of crosstalk interference in MIMO channels.
