A Structured Fixed-Rate Vector Quantizer Derived from Variable- Length Encoded Scalar Quantizers
The well-known error propagation problem inherent in any variable-length coding operation limits the usefulness of variable-length encoded entropy-constrained scalar quantizers when the quantizer outputs are to be transmitted ...
Joint Design of Block Source Codes and Modulation Signal Sets
We consider the problem of designing a bandwidth-efficient, power-limited digital communication system for transmitting information from a source with known statistics over a noisy waveform channel. Each output vector of ...
Variable-Rate Finite-State Vector Quantization
A finite-State vector quantizer is a finite-state machine that can be viewed as a collection of memoryless full-searched vector quantizers, where each input vector is encoded using a vector quantizer associated with the ...
