Abstract： |
This invention is a multimedia broadcasting system and its realizing method that facing mobile terminal. It belongs to multimedia broadcasting field. Its feature is that it is based on orthogonal frequency division multiplexing¡ªmultiple channel system. multiple broadcasting service is provided to mobile terminal by the IFFT of emission terminal and the FFT of receive terminal. The transformation is done by allocating different channels on different sub carrier wave groups by using the frequency range of existing common television broadcasting system and big zone broadcasting type. It can provide media program of scores of channels efficiently and economically, and the utility factor is high. Individualization broadcasting can be realized for different quality needs subscriber. Dynamic power control, modulation, forward error correction encoding and frequency hopping can be realized to ensure the transmission quality. The receive terminal can be simply design and the power consumption can be reduced in this invention. |
