Embodiment Construction
[0035] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0036] A schematic diagram of an embodiment of signal transmission between a transmitter and a receiver according to the anti-jamming digital mobile broadcast signal transmission method proposed by the present invention, as shown in FIG. figure 1 shown, follow these steps:
[0037] 1) The certain anti-interference digital mobile broadcast signal 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 the input data bit stream;
[0038] 2) The certain anti-jamming digital mobile broadcast signal transmitter passes its input data bit stream through RS coding, convolutional interleaving, serial concatenated multi-code rate punctured convolutional coding, symbol modulation and symbol ro...
