Baseband and RF hardware impairments in full-duplex wireless systems: experimental characterisation and suppression

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Andrew Charles Mallory Austin, Pavle Belanovic

Hardware imperfections can significantly reduce the performance of full-duplex wireless systems by introducing non-idealities and random effects that make it challenging to fully suppress self-interference. Previous research has mostly focused on analysing ...

Distributed average consensus with quantization refinement

Pascal Frossard, Ye Pu, Effrosyni Kokiopoulou

We consider the problem of distributed average consensus in a sensor network where sensors exchange quantized information with their neighbors. We propose a novel quantization scheme that exploits the increasing correlation between the values exchanged by ...

One-Bit Measurements With Adaptive Thresholds

Michaël Unser, Arash Amini, Ulugbek Kamilov, Aurélien Bourquard

We introduce a new method for adaptive one-bit quantization of linearmeasurements and propose an algorithm for the recovery of signals based on generalized approximate message passing (GAMP). Our method exploits the prior statistical information on the sig ...

Progressive quantization in distributed average consensus

Pascal Frossard, Effrosyni Kokiopoulou

We consider the problem of distributed average consensus in a sensor network where sensors exchange quantized information with their neighbors. In particular, we exploit the increasing correlation between the exchanged values throughout the iterations of t ...

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 ...

Low-distortion switched-capacitor event-driven analogue to-digital converter

Alexandre Schmid, Yusuf Leblebici, Vahid Majidzadeh Bafar

An event-driven analogue-to-digital converter (ADC) architecture is proposed. The proposed architecture has less sensitivity to amplifier and DAC nonlinearity, and reduces the swing and dynamic common-mode range requirement of the operational transconducta ...

Analysis of pulse modulation format in coded BOTDA sensors

Marcelo Alfonso Soto Hernandez

A theoretical and experimental analysis of the impact of pulse modulation format on Brillouin optical time-domain analysis (BOTDA) sensors using pulse coding techniques has been carried out. Pulse coding with conventional non-return-to-zero (NRZ) modulatio ...

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 ...
