TUNER AND METHOD FOR CROSSTALK CANCELLATION

摘要

A tuner for crosstalk cancellation comprises a plurality tuner units and a crosstalk cancellation unit, wherein the crosstalk cancellation unit is connected to each tuner unit. Tuner units are used for receiving analog signals with same frequency band or different frequency bands respectively, and converting the analog signal to a digital signal. The crosstalk cancellation unit receives digital signals from each tuner unit, and executes operation or algorithm of each digital signal to cancel the crosstalk of each analog signal on tuner units and/or analog front ends.
