Multiple Description Quantizer Design Using A Channel Optimized Quantizer Approach

This paper extends the channel optimized quantization scheme of Farvardin and Vaishampayan [1] to two parallel channels. The extended multiple-channel optimized quantizer design (MCOQD) framework is applied to discrete memoryless channels with erasures. The resultant MCOQD subsumes the multiple description scalar quantizer (MDSQ) design of Vaishampayan [2]. While MDSQ is suited to only “on-off”...

Quantizer design for distributed estimation with communication constraints and unknown observation statistics

We consider the problem of quantizer design in a distributed estimation system with communication constraints in the case where only a training sequence is available. Our approach is based on a generalization of regression trees. The lookahead method that we also propose improves significantly the performance. The final system performs similarly to the one that assumes known statis-

Joint design of a channel-optimized quantizer and multicarrier modulation

We present an algorithm for design of a joint source-channel coder using a channel-optimized quantizer and multicarrier modulation. By changing the power of each subchannel in the multicarrier modulation system, different degrees of error protection can be provided for different bits according to their importance. The algorithm converges to a locally optimum system design. Compared to a Lloyd–M...

Consensus Algorithm Design for Distributed Estimation

In this paper we study the problem of designing optimal consensus algorithms for distributed estimation of dynamical systems. In particular, we show that for fixed estimation gain, the problem of finding optimal consensus matrix is convex and can be efficiently performed numerically. We also provide some numerical examples to common scenarios, like symmetric geometric random graphs, which are r...

Quantizer Design for Interconnected Feedback Control Systems

In this paper, we consider design of interconnectedH∞ feedback control systems with quantized signals. We first assume that a decentralized state feedback has been designed for an interconnected continuous-time LTI system so that the closed-loop system is stable and a desired H∞ disturbance attenuation level is achieved, and that the subsystems’ states are quantized before they are passed to th...
