Abstract:
    This invention relates to a communication method in a single-multiple carrier harmony digital broadcast system suitable for the digital broadcast system with two working modes of single-carrier and multi-carrier existing at the same time, at the transmission end, since the system is divided into two working modes, different working modes require different structures of signal frames and this invention applies a specific signal frame head to be compatable with the two modes, at the receiving end, first of all, correlated operation is done to the local sequence and received sequence to finish timing synchronization then to apply related channel estimation method and balance according to different working modes of single-multi-carrier.
