Embodiment Construction
[0031] refer to figure 1. The fractional interval adaptive blind equalization digital logic circuit with decision feedback is used to receive the oversampled baseband signal to be equalized in parallel, and the equalization coefficient lag update structure and the equalization structure combining fractional interval and decision feedback are used to perform digital sampling on the baseband signal. To process and time-domain equalize the broadband signal, the entire circuit includes a forward equalization unit, a reverse equalization unit, a decision unit, an adaptive algorithm unit, a data assignment unit, a summation unit and an error extraction unit.
[0032] The equalization method consists of a serial processing flow and two loop feedback processing flow implementations:
[0033] The serial processing flow consists of a data assignment unit, a forward equalization unit, and a summation unit connected in series.
[0034] The main function of the data assignment unit is t...
