Primary Voltage Control in Active Distribution Networks via Broadcast Signals: The Case of Distributed Storage

Jean-Yves Le Boudec, Mario Paolone, Dan-Cristian Tomozei, Konstantina Christakou, Maryam Bahramipanah

In this paper, we consider an active distribution network (ADN) that performs primary voltage control using real-time demand response via a broadcast low-rate communication signal. The ADN also owns distributed electrical energy storage. We show that it is ...

Cooperative Relaying at Finite SNR–-Role of Quantize-Map-and-Forward

Christina Fragouli, Ayan Sengupta, I-Hsiang Wang

Quantize-Map-and-Forward (QMF) relaying has been shown to achieve the optimal diversity-multiplexing trade-off (DMT) for arbitrary slow fading full-duplex networks as well as for the single-relay half-duplex network. A key reason for the DMT-optimality of ...

Non-Uniform Speech/Audio Coding Exploiting Predictability of Temporal Evolution of Spectral Envelopes

Petr Motlicek, Hynek Hermansky, Sriram Ganapathy

Unlike classical state-of-the-art coders that are based on short-term spectra, our approach uses relatively long temporal segments of audio signal in critical-band-sized sub-bands. We apply auto-regressive model to approximate Hilbert envelopes in frequenc ...
