DEVICE AND METHOD FOR RECEIVER OF HYBRID SIGNAL

PURPOSE: An apparatus and a method for receiving a ground wave signal and a mobile signal are provided to receive two signals in an environment in which a ground wave signal and a mobile signal are combined. CONSTITUTION: A tuner unit(20) converts a selected frequency into an IF signal. An analog to digital converter(30) converts the IF signal into a digital signal. A demodulator(40) demodulates the digital signal outputted from the analog to digital convertor. An equalization unit(50) detects a training signal from an output signal of the demodulator. The equalization unit estimates a transmission channel. The equalization unit compensates distortion existing in mobile signal data and ground wave signal data.
