Abstract:
1. A Digital Terrestrial Multimedia Broadcasting (DTMB)-based control system, comprising: a carrier mode detector, for receiving (M+N) input signals to thereby produce an amplitude sign signal and a carrier sign signal and determining a carrier mode to be multi-carrier mode or single-carrier mode based on the amplitude sign signal and the carrier sign signal, where M indicates the number of TPS signals corresponding to the i-th frame in wireless transmission, N indicates the number of carrier signals corresponding to the i-th frame; a TPS decoder, for receiving the M input signals and determining a codeword index signal corresponding to the M input signals; a first latch, connected to the carrier mode detector, for locking the amplitude sign signal and the carrier sign signal; a second latch, connected to the TPS decoder, for locking the codeword index signal; and a latch controller, connected to the carrier mode detector, the TPS decoder, the first latch and the second latch, for driving the first latch to lock the amplitude sign signal and the carrier sign signal or driving the second latch to lock the codeword index signal.
