| Summary: | and verified by simulation using Gauss-Markov sources. A based speech coders are used for the transmission of speech both channels are working a high quality reconstruction of code is applied to decrease the operating channel SNR DPCM is a system that uses diversity to overcome channel erasures we show that the MR-DPCM system is more robust than frames over frame erasure channels. For simple frame impairments. In this thesis the design for a two channel is down a lower quality description is obtained. The is sent to the receiver over the two available channels. If MR-DPCM system is then obtained for different code rates and necessary for mutual refinement are derived. The MR-DPCM operating at 24 kbps and 32 kbps are constructed. The performance of a single channel ADPCM system. The MR-DPCM performance of MR-DPCM speech coders is compared to the performance of the MR-DPCM system is analyzed theoretically, significantly. The performance of the Reed-Solomon coded sub-optimum MR-DPCM scheme is also analyzed, and conditions system and its applications to frame erasure channels. MR- system is addressed. Two descriptions of the source sequence system is modified to code speech, and speech coders system to transmit speech over a mobile radio channel model the single channel ADPCM system. We then apply the MR-DPCM the source sequence is obtained. In case one of the channels vehicle speeds. We consider the design of a mutually refining DPCM (MR-DPCM) where frame erasures occur in bursts. A Reed-Solomon channel |
