Study of Field Misalignment in a Cavity Used for Atomic Clock Applications

In vapor cell atomic clocks the atom-field interaction is typically obtained inside a microwave cavity resonator in which the microwave driving field together with a static magnetic field and an optical field are applied to excite the atoms. These fields a ...

Simple Relaying Strategies for Half-duplex Networks

Christina Fragouli, Ayfer Özgür Aydin, Siddhartha Brahma

We consider the diamond network where a source communicates with the destination through N non-interfering half-duplex relays. Using simple outer bounds on the capacity of the network, we show that simple relaying strategies having exactly two states and a ...

A Navigation-Grade MEMS Accelerometer based on a Versatile Front End

Maher Kayal, Marc Pastre

This paper presents a MEMS-based 5th-order Delta Sigma capacitive accelerometer. The Delta Sigma loop is implemented in mixed signal, the global 5th-order filter having a 2nd-order analog and a 3rd-order digital part. The system can be used with a wide ran ...

A 300Hz 19b DR capacitive accelerometer based on a versatile front end in a 5th-order ΔΣ loop

Maher Kayal, Marc Pastre

This paper presents a 5th-order ΔΣ capacitive accelerometer. The ΔΣ loop is implemented in mixed signal, the global 5th-order filter having a 2nd-order analog and a 3rd-order digital part. The system can be used with a wide range of sensors, because the mi ...

In vivo 1H NMR spectroscopy of the human brain at high magnetic fields: Metabolite quantification at 4T vs. 7T

Rolf Gruetter

A comprehensive comparative study of metabolite quantification from the human brain was performed on the same 10 subjects at 4T and 7T using MR scanners with identical consoles, the same type of RF coils, and identical pulse sequences and data analysis. Si ...

Interval consensus: from quantized gossip to voting

Martin Vetterli, Patrick Thiran, Florence Bénézit

We design distributed and quantized average consensus algorithms on arbitrary connected networks. By construction, quantized algorithms cannot produce a real, analog average. Instead, our algorithm reaches consensus on the quantized interval that contains ...

Achieving Linear Scaling with Interference Alignment

Ayfer Özgür Aydin

Recent results have shown that interference alignment can achieve K/2 degrees of freedom in a K-user interference channel with time or frequency varying channel coefficients. For fixed number of users K, the number of degrees of freedom characterizes the a ...

Achievable Rates for Conferencing Multiway Channels

Michael Christoph Gastpar

A generalization of the additive Gaussian two-way channel to M users is considered. Such channels contain implicit feedback in the sense that the channel output signals observed by the different encoders are correlated. While the benefits of feedback are s ...

On the mutual information and low-SNR capacity of memoryless noncoherent Rayleigh-fading channels

Ninoslav Marina

The memoryless noncoherent single-input-single-output (SISO) Rayleigh-fading channel is considered. Closed-form expressions are derived for the mutual information between the output and the input of this channel when the input magnitude distribution is dis ...

Two-Dimensional Spatio-Temporal Signal Processing for Dispersion Compensation in Time-Stretched ADC

Ali H. Sayed

Time-stretched analog-to-digital converters (ADCs) have offered revolutionary enhancements in the performance of electronic converters by reducing the signal bandwidth prior to digitization. An inherent limitation of the time-stretched ADC is the frequency ...
