Embodiment Construction
[0032] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0033] A schematic diagram of an embodiment of signal transmission between a certain transmitter and a receiver of a digital broadcast wireless signal anti-fading transmission method according to the present invention, as shown in FIG. figure 1 shown, follow these steps:
[0034] 1) The digital broadcast wireless signal anti-fading 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;
[0035] 2) The certain digital broadcast wireless signal anti-fading transmitter forms FFT concatenated interleaving coded modulation in the frequency domain after its input data bit stream undergoes RS coding, convolutional interleaving, LDPC coding, symbol modulation, and s...
