Example Embodiment
[0031] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0032] A schematic diagram of an embodiment of signal transmission between a transmitter and a receiver of the anti-fading digital mobile broadcast signal transmission method according to the present invention, such as figure 1 As shown, proceed as follows:
[0033] 1) The certain anti-fading 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 an input data bit stream;
[0034] 2) The certain anti-fading digital mobile broadcast signal transmitter streams its input data bits through RS coding, convolutional interleaving, multi-rate punctured convolutional coding, symbol modulation and symbol rotation, and symbol interleaving. The FFT cascaded interl...
