| Summary: | and we study its applications to sources with memory. The are working, under a constraint on the quality received when both channels are working, and of the distortion when one channel is down, in the case of uniform, non-uniform and channels, and in the case of two channels, which is the case considered in this thesis, the principal objective is to derivation of closed-form expressions of the distortion when Description Scalar Quantizer (MDSQ) for a memoryless source, entropy-constrained quantizations. These results are then for a packet switched network in which packets may be lost, impairments: the information is transmitted on different MDSQ is a system which uses diversity to overcome channel multiple description transform codes as well as multiple de obtain the highest quality at the receiver when both channels obtained as compared to existing methods. one channel is down. We consider a memoryless source and we optimal bit allocation problem is solved. Finally, we apply scription sub-band codes to real speech. We demonstrate that show that at high rates, relevant approximations allow the significant improvements in reconstructed speech quality are transform codes for sources with memory and an associated used to analyze the performance of multiple description We consider the performance at high rates of the Multiple |
