Abstract :
We propose a joint source-channel content-based multistream video coding scheme to combat transmission errors. By coupling it with our ground breaking innovation frequency-hopping OFDM at the physical layer, our proposed multistream design provides better error protection than the conventional design. Note that the frequency-hopping OFDM provides a significantly superior platform to all other existing technologies, including cdma2000 and WCDMA, for wireless services. Simulations demonstrate that our design outperforms the single stream layered design by 3-7 dB under harsh network conditions.
