Blind equalization tap coefficient adaptation in optical systems
摘要：
A method of blind tap coefficient adaptation includes receiving a digital data signal including random digital data, equalizing a first portion of the digital data signal using a first set of predetermined tap coefficients and a second portion of the digital data signal using a second set of predetermined tap coefficients. The method includes generating a first eye diagram and a second eye diagram from a first portion and a second portion of an equalized signal, respectively. The first eye diagram is compared with the second eye diagram to determine which of the sets of predetermined tap coefficients results in a data signal having a higher signal quality. The method includes inputting to an equalizer as an initial set of tap coefficients the first set of predetermined tap coefficients or the second set of predetermined tap coefficients according to the determination.

盲抽头系数适配的方法包括：接收包括随机数字数据的数字数据信号，使用第一组预定抽头系数对数字数据信号的第一部分进行均衡，以及使用第二组预定的抽头系数的数字数据信号的第二部分 抽头系数。 该方法包括分别从均衡信号的第一部分和第二部分生成第一眼图和第二眼图。 将第一眼图与第二眼图进行比较，以确定预定抽头系数中的哪一组导致具有较高信号质量的数据信号。 该方法包括根据该确定，将均衡器作为初始抽头系数集合输入第一组预定抽头系数或第二组预定抽头系数。
