The Chinese digital terrestrial/television multimedia broadcasting (DTMB) standard adopts time-domain synchronous orthogonal frequency division multiplexing (TDS-OFDM) as the modulation technology. TDS-OFDM system uses time domain PN sequences as frame header and thus has to employ square root raised cosine (SRRC) filters to perform spectrum shaping. In order to ensure synchronization performance,...
In [1], an orthogonal frequency division multiplexing (OFDM) preamble based on distance detection (PBDD) is proposed for broadcasting systems. However, traditional correlation based signaling demodulation will completely fail to work under severe transmission conditions with ultra-long delay spread 0dB echo. In this paper, a new transmission parameter signaling (TPS) detection method is proposed for...
