Power Optimized Space-Time Code for Layer Coded Multimedia over Wireless Channels
A power optimized space-time code is presented for reliable delivery of layer coded multimedia data through wireless channels. Appropriate power control further improves the performance of space time coding. By allocating transmitted power according to the layer perceptual importance, unequal error protection is achieved. Numerical example shows that the proposed algorithm achieves 6dB PSNR improvement compared to that with equal power distribution in low SNR range.
