Embodiment Construction
[0030] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0031] A schematic diagram of an embodiment of signal transmission between a certain transmitter and a receiver of the digital broadcast wireless signal anti-interference transmission method proposed by the present invention, as shown in FIG. figure 1 shown, follow these steps:
[0032] 1) The digital broadcast wireless signal anti-interference transmitter converts the multimedia data stream into a bit stream through the media data processor, and uses the scrambling code sequence generated by the feedback shift register to perform scrambling processing to form an input data bit stream;
[0033] 2) The certain digital broadcast wireless signal anti-jamming transmitter forms an FFT bit-interleaved coded modulation data block in the frequency domain after undergoing multi-rate punctured convolutional coding, bit interleaving, and symbol modulatio...
