    At first I thought it was impossible. At relatively short distances the S/N ratio would be so low that even if the signal was detected it could not be decoded.
    Of course, there are algorithms that allow to decode signals with negative S/N ratio, if there is redundancy in the information, but this requires that the sender intentionally transmits the signal with redundancy.
    After reading the paper, I changed my mind. The author suggests that each show is transmitted several times from different TV broadcasters and this would provide the redundancy.
    I am not skeptical anymore.
