Abstract
(EN)
For ATSC 3.0, a frame comprises bootstrap OFDM symbols, having known universal OFDM parameters, followed by a preamble and payload data, which may have different OFDM characteristics. In the context of ATSC, the present application proposes to insert a transmitter identifier (TxID) within this frame structure. In SFN networks, such a TxID enables a receiver to adapt antennas orientation, or can improve network synchronization between nodes, or be used to derive the receiver location. Two options for said TxID insertion are proposed: The first option makes use of an additional fifth bootstrap symbol conveying the TxID instead of the conventional signaling information. The second option uses an additional OFDM symbol immediately prior or after the preamble, said additional OFDM symbol being generated similarly to the bootstrap symbol, except that the PN sequence is replaced by a Gold sequence uniquely determined by the TxID. At the receiver, TxID detection can be performed either using time domain or frequency domain code correlation.
