APPLICATIONS OF SIGNAL ANALYSIS USING AUTOREGRESSIVE MODELS FOR AMPLITUDE MODULATION

Petr Motlicek, Hynek Hermansky, Sriram Ganapathy, Samuel Thomas

Frequency Domain Linear Prediction (FDLP) represents an efficient technique for representing the long-term amplitude modulations (AM) of speech/audio signals using autoregressive models. For the proposed analysis technique, relatively long temporal segment ...

Autoregressive Models of Amplitude Modulations in Audio Compression

Petr Motlicek, Hynek Hermansky, Sriram Ganapathy

We present a scalable medium bit-rate wide-band audio coding technique based on frequency domain linear prediction (FDLP). FDLP is an efficient method for representing the long-term amplitude modulations of speech/audio signals using autoregressive models. ...

CPT spectroscopy on low-temperature sealed MEMS rubidium vapour cells

Nico de Rooij, Herbert Shea, Thomas Maeder, Yves Pétremand, Frank Seigneur

In recent years there has been a strong effort to reduce the size and power consumption of vapour cell atomic clocks [1,2]. The progress in this direction is driven by several factors such as the use low power laser diodes (VCSEL), Coherent Population Trap ...

Polar codes for channel and source coding

Satish Babu Korada

The two central topics of information theory are the compression and the transmission of data. Shannon, in his seminal work, formalized both these problems and determined their fundamental limits. Since then the main goal of coding theory has been to find ...

Drift-free magnetic equilibrium reconstruction using the response to plasma position modulation

Jonathan Bryan Lister

Inductive magnetic sensors are widely used for plasma equilibrium reconstruction and control. However, their measurements involve electronic integration and can therefore experience drift leading to inaccurate plasma positioning. For this reason, we have s ...

Approximate Capacity of a Class of Gaussian Relay-Interference Networks

Suhas Diggavi

In this paper we study the Gaussian relay-interference network, in which relay (helper) nodes are to facilitate competing information flows over a wireless network. We examine this problem for certain regimes of channel values, when one of the cross-links ...

Coding along Hermite polynomials for interference channels

Emmanuel Abbé

This paper analyzes the use of non-Gaussian input distributions over the Gaussian interference channel. It has been recently proved that the iid Gaussian code ensemble together with a decoder that treats interference as noise is sum-capacity achieving, if ...

Phase–frequency detecting time-to-digital converter

Kyojin Choo

A simple time-to-digital converter (TDC), capable of detecting not only phase difference but also frequency difference, is presented. The proposed TDC guarantees pull-in even for PLLs with the lowest loop gain. The TDC is fabricated in a 65 nm CMOS process ...

On the Combination of Auditory and Modulation Frequency Channels for ASR applications

Hynek Hermansky, Fabio Valente

This paper investigates the combination of evidence coming from different frequency channels obtained filtering the speech signal at different auditory and modulation frequencies. In our previous work \cite{icassp2008} ...
