In this paper, the situation in which a receiver has to execute a task from a quantized version
of the information source of interest is considered. The task is modeled by the minimization …

In this paper, we introduce the problem of decision-oriented communications, that is, the
goal of the source is to send the right amount of information in order for the intended …

Optimal scalar quantization subject to an entropy constraint is studied for a wide class of
difference distortion measures including rth-power distortions with r> 0. It is proved that if the …

A multigrid framework for the one-dimensional (scalar) fixed-rate quantization problem is
presented. The framework is based on the Lloyd-Max iterative process, which is a central …

In case of wideband communications the analog-to-digital converter becomes a power
consumption implementation bottleneck. Alternatively, transmission schemes based on …

The performance of systems where multiple users communicate over wireless fading links
benefits from channel-adaptive allocation of the available resources. Different from most …

The nearest neighbor condition implies that when searching for a mean-square optimal fixed-
rate quantizer it is enough to consider the class of regular quantizers, ie, quantizers having …

In this paper designs of two types of quantizers are presented. The first type is designed to
minimize a distortion measure under the constraint that the number of levels is fixed or the …

A note on optimal quantization (Corresp.) Page 1 +Ds+D9, D+D’+D’, D+D2+D3+D6+D7+D8+D9]
Every permutation of the columns of this matrix yields a matrix thus y = 9 and the Corollary to …

We consider optimal scalar quantization with rth power distortion and constrained Rényi
entropy of order α. For sources with absolutely continuous distributions the high rate …
