| Summary: | accommodate the distinct distributions of the coefficients. accomplish the variable length coding of the DCT coefficients allocations. We also discuss various strategies for and Lloyd-Max quantizers are constructed. We consider the as well as subjective listening tests. Additionally, we Both employ the discrete cosine transform (DCT) to channel coding. coding MDSQ system, DCT coefficient distributions are modeled construct two different types of MDSQ-based systems: a fixed correlated Rayleigh fading channels. In this thesis, we decorrelate blocks of sampled speech. For the fixed length description quantizer. In the variable length coding system, employing error detection that takes advantage of the exploiting the structure and redundancy of the multiple length coding system and a variable length coding system. measures such as the segmental signal-to-noise ratio (SEGSNR) offer comparisons between our MDSQ system and another performance of both speech coding systems using objective performance tradeoff between fixed and adaptive bit proposed system that uses dynamic bit allocation subband quantizers with optimized reconstruction levels. We residual redundancy in arithmetic codes. We measure the speech coding and rate-compatible punctured convolutional using Shannon-Fano-Elias (arithmetic) coding modified to utilizing multiple description scalar quantizers (MDSQ) for we build a set of entropy-constrained, uniform threshold We obtain performance improvements in this system by |
