Abstract:
The present invention relates to an apparatus and method for simultaneous channel estimation in a digital broadcast system based on a single frequency networkThe present specification encloses a receiver simultaneously acquiring channel responses for each subchannels including a certain number of pilot subcarriers in the frequency and time domain direction from frames transmitted with at least one signalIn the present invention, a receiving apparatus in the single frequency broadcast network may simultaneously estimate the channels of adjacent transmitters, and receiving CNR is enhanced by detecting MIMO signal by the estimated channel.
