METHOD AND APPARATUS FOR RECEIVING COUPLED SIGNAL OF TERRESTRIAL SIGNAL AND MOBILE SIGNAL |
摘要 |
A receiving apparatus estimates a transmission channel of a signal through a training signal that is inserted into a data area of a received multipath signal, i.e., a mobile signal and a terrestrial signal that is coupled to the mobile signal, and estimates a transmission channel by detecting a received mobile signal using a previously equalized signal of a mobile signal and a transmitting signal corresponding to a terrestrial signal that is coupled to the mobile signal through determined data. Mobile signal data corresponding to training signal distortion existing in terrestrial signal data are compensated based on a channel estimation value. |

1. A receiving apparatus of a coupled signal of a terrestrial signal and a mobile signal, the receiving apparatus comprising:
an antenna that receives a mobile signal and a terrestrial signal that are transmitted with one channel; a tuner that selects a desired frequency of the received signal by tuning and that converts the received signal to an intermediate frequency signal; an analog to digital converter (A/D converter) that converts the intermediate frequency signal that is converted in the tuner to a digital signal; a demodulation unit that demodulates and outputs the digital signal that is output from the A/D converter; and an equalization processor that estimates a transmission channel by detecting a training signal of the mobile signal and the terrestrial signal from an output signal of the demodulation unit and that compensates distortion existing in mobile signal data and terrestrial signal data. |
