SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD AND PROGRAMME Russian patent published in 2016 - IPC H04J11/00 

FIELD: radio engineering, communication.

SUBSTANCE: present invention relates to a signal processing device, a signal processing method and a programme carrier configured for corresponding demodulation of the required signal from a multiplexed signal obtained by multiplexing a plurality of signals. A preamble signal is detected from a multiplexed signal obtained by multiplexing a plurality of signals. When information for distinguishing each of the signals, which is contained in the preamble signal, indicates a first signal, demodulation by a demodulator continues and the first signal is demodulated. When information for distinguishing each of the signals, which is contained in the preamble signal, indicates a second signal, demodulation is not performed by stopping demodulation by the demodulator. The present technique can be applied to a signal processing device, which processes signals for digital broadcasting.

EFFECT: reduced circuit size and power consumption.
