Title:
DIGITAL FRONT-END EQUALIZATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/128167
Kind Code:
A1
Abstract:
Embodiments of the present invention relate to the technical field of communications, and in particular, to a digital front-end equalization method and device. The method comprises: reading an equalization sequence received by an equalization sequence receiving end; performing frequency domain transformation on the read equalization sequence of a channel undergoing equalization and a pre-stored reference equalization sequence, so as to obtain a frequency domain equalization sequence of the channel undergoing equalization and a reference frequency domain equalization sequence, respectively; determining a frequency domain response of the channel undergoing equalization on the basis of the frequency domain equalization sequence of the channel undergoing equalization and the reference frequency domain equalization sequence; determining, according to the frequency domain response, an equalization coefficient corresponding to the channel undergoing equalization; and performing equalization processing on the channel undergoing equalization according to the equalization coefficient. The method selects an equalization sequence and a pre-stored reference sequence rather than using an equalization sequence of any channel as a reference sequence. Therefore, the method is unaffected by the reference channel, and thus eliminates the effect of channel equalization on system performance, thereby improving system performance.
