| 1. A method of receiving digital television (TV) signals, the method comprising:
receiving a plurality of incident data signals at a plurality of antennas;
demodulating the incident data signals;
estimating a channel for at least one of the antennas in response to the demodulated incident data signals;
selecting a main path signal from among the demodulated incident data signals and performing beam-forming on the selected
main path signal; and
combining the beam-formed selected main path signal with the demodulated incident data signals to form an output signal.
