Embodiment Construction

[0034] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] A schematic diagram of an embodiment of signal transmission between a transmitter and a receiver according to the anti-noise digital mobile broadcasting signal transmission method proposed by the present invention, as shown in FIG. figure 1 shown, follow these steps:

[0036] 1) The certain anti-noise digital mobile broadcast signal transmitter converts the multimedia data stream into a bit stream through a 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;

[0037] 2) The certain noise-resistant digital mobile broadcast signal transmitter forms an FFT bit-interleaved coded modulation data block in the frequency domain after its input data bit stream undergoes LDPC encoding, bit interleaving, symbol modulation and symbol ...
