Abstract： |
An anti-attenuation method based on code stream rearrangement in wireless multimedia communication is disclosed. At transmitting end, the adaptive aditing regulation of data stream is performed before the video data stream comes into channel encoder or modulator. At the receiving end, the code stream is reversely rearranged to restore original data stream before it comes into information source decodar or channel decoder. Said adaptive regulation can be performed according to channel and information source characterstics. Its advantages include high anti-attenuation effect, high transmission reliability, and low complexity. |
