Abstract

A new feed forward equalization (FFE) method for four-level pulse-amplitude modulation signal (PAM4) is introduced. The new FFE method equalizes the signal by bit instead of by symbol which provide the better high frequency compensation in some situations. The advantages and limitations of per bit FFE is discussed and compared against per symbol FFE. Several test cases are presented to show the advantages and limitations of the new FFE method.

高速设计中多级信号的每比特均衡方法

介绍了一种新的四电平脉冲调幅信号前馈均衡(FFE)方法。该方法采用位均衡代替符号均衡，在某些情况下能提供较好的高频补偿。讨论了每比特FFE的优点和局限性，并与每符号FFE进行了比较。给出了几个测试用例来说明新的FFE方法的优点和局限性。
