具有正交幅度调制的基于阵列读取器的磁记录系统
摘要：
一种磁记录系统包括：模拟输入阵列，其能够操作来接收从磁存储介质取得的模拟信号；正交幅度调制器，其能够操作来组合所述模拟信号来产生正交幅度调制信号；正交幅度解调器，其能够操作来与所述阵列的每个通道对应地从所述正交幅度调制信号产生多个解调信号；和联合均衡器，其能够操作来对多个解调信号滤波，来产生均衡的输出。
摘要（英）：

A magnetic recording system includes an array of analog inputs operable to receive analog signals retrieved from a magnetic storage medium, a quadrature amplitude modulator operable to combine the analog signals to yield a quadrature amplitude modulated signal, a quadrature amplitude demodulator operable to yield a plurality of demodulated signals from the quadrature amplitude modulated signal corresponding to each channel of the array, and a joint equalizer operable to filter the plurality of demodulated signals to yield an equalized output.
