A single acquisition channel receiver for GPS L1CA and L2C signals based on orthogonal signal processing Universiteit Gent
All GPS civilian signals are transmitted from the same GPS Satellite Vehicles constellation. It is desirable, especially in commercial GNSS receivers, to have more than one of these signals acquired by the same receiver so to assure better signal acquisition and improved reliability at wider operating areas. This paper proposes the integration of the received GPS L1CA and L2C signals orthogonally to enable acquiring them in a single processing ...
A 13µA analog signal processing IC for accurate recognition of multiple intra-cardiac signals KU Leuven
A low-power analog signal processing IC is presented for the low-power heart rhythm analysis. The ASIC features 3 identical, but independent intra-ECG readout channels each equipping an analog QRS feature extractor for low-power consumption and fast diagnosis of the fatal case. A 16-level digitized sine-wave synthesizer together with a synchronous readout circuit can measure bio-impedance in the range of 0.1-4.4 kΩ with 33 mΩ(rms) resolution and ...

Opportunities and Challenges of Digital Signal Processing in Deeply Technology-Scaled Transceivers Vrije Universiteit Brussel KU Leuven
The ever improving cost advantages and processing capabilities of the technology have been happening according to the so-called Moore's Law. Although digital circuits can significantly benefit from the aggressive scaling, it is very controversial for analog circuit. However, analog circuit still has to follow the scaling trend because a single chip integration offers key commercial advantages. To optimally achieve the best performance/power/cost ...
Signal Processing Challenges for Emerging Digital Intensive and Digitally Assisted Transceivers with Deeply Scaled Technology Vrije Universiteit Brussel
Mainstream foundries are leaping toward 14nm node and beyond. Although aggressive scaling can substantially improve digital circuit, it is very controversial for analog circuit. However, analog circuit still has to follow the scaling trend because a single chip integration offers key commercial

Augmenting Social Interactions: Realtime Behavioural Feedback using Social Signal Processing Techniques Universiteit Hasselt
Nonverbal and unconscious behaviour is an important component of daily human-human interaction. This is especially true in situations such as public speaking, job interviews or information sensitive conversations, where researchers have shown that an increased awareness of one’s behaviour can improve the outcome of the interaction. With wearable technology, such as Google Glass, we now have the opportunity to augment social interactions and ...
Silicon-organic hybrid (SOH) devices for nonlinear optical signal processing Universiteit Gent
Silicon-on-insulator (SOI) is a promising material system for dense on-chip integration of both silicon photonic and electronic devices. The high refractive index of silicon enables strong light confinement and compact low-loss devices at telecommunication wavelengths. In addition, on-chip nonlinear optical signal processing becomes feasible, because the third-order nonlinear susceptibility chi((3)) of silicon is about 200 times that of glass, ...
Physiological Signal Processing for Emotional Feature Extraction Vrije Universiteit Brussel
This paper introduces new approaches of physiological signal processing prior to feature extraction from electrocardiogram (ECG) and electromyography (EMG). Firstly a new signal denoising approach based on the Empirical mode decomposition (EMD) is presented. The EMD can decompose the noisy signal into a number of Intrinsic Mode Functions (IMFs). The proposed algorithm estimates the noise level of each IMF. Experiments show that the proposed ...
200 mm wafer scale III-V/SOI technology for all-optical network-on-chip and signal processing Universiteit Gent
Integrated components, including microdisk lasers, photodetectors, and wavelength selective circuits, for optical network-on-chip and all-optical signal processing are presented using a complementary metal-oxide-semiconductor compatible III-V/silicon-on-insulator integration technology at 200mm wafer scale.
