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 certain transmitter and a receiver according to the anti-noise mobile digital broadcasting signal transmission method proposed by the present invention, as shown in FIG. figure 1 shown, follow these steps:

[0037] 1) The certain anti-noise mobile digital 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;

[0038] 2) The certain anti-noise mobile digital broadcast signal transmitter forms an FFT encoded data block in the frequency domain after its input data bit stream undergoes LDPC encoding, symbol modulation and symbol rotation. FFT stands for Fast Discrete F...
