Embodiment Construction
[0031] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0032] According to the embodiment of the signal transmission between the transmitter and the receiver of the digital broadcast single frequency network anti-jamming mobile signal transmission method proposed by the present invention (assuming that there are N transmitters in the single frequency network), as figure 1 shown, follow these steps:
[0033] 1) The central data manager of the single frequency network 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 network data manager of the single frequency network forms an FFT bit-interleaved coded modulation data block in the frequency domain through multi-rate punctured convolutional coding, bit ...
