CPT Cesium-Cell Atomic Clock Operation With a 12-mW Frequency Synthesizer ASIC

Pierre-André Farine, Steve Tanner, Yazhou Zhao

In this paper, we present the design, fabrication, and electrical characterization of a low-power microwave source for interrogation of cesium atomic hyperfine transition frequency using the coherent population trapping (CPT) technique. The 4.6-GHz frequen ...

All-optical signal processing using dynamic Brillouin gratings

Luc Thévenaz, Sang Hoon Chin, Nikolay Primerov

The manipulation of dynamic Brillouin gratings in optical fibers is demonstrated to be an extremely flexible technique to achieve, with a single experimental setup, several all-optical signal processing functions. In particular, all-optical time differenti ...

Generation and application of dynamic gratings in optical fibers using stimulated Brillouin scattering

Luc Thévenaz, Nikolay Primerov

Since the invention of optical fiber cable data transmission using light has become ubiquitous in the past years. Nonlinear optical effects, which are hardly noticed in our daily life, have become crucial and highly influential for the design and performan ...

A 2.4-GHz MEMS-Based PLL-Free Multi-Channel Receiver With Channel Filtering at RF

Christian Enz, Aravind Prasad Heragu Singaiyengar

A Bulk Acoustic Wave (BAW) resonator based 2.4-GHz low power receiver is presented in this work. The intrinsic high quality factor ( Q) of the BAW resonator (around 400 at 2.4-GHz) is exploited to provide channel selection at RF and in the frequency synthe ...

Slow light fiber systems in microwave photonics

Luc Thévenaz, Sang Hoon Chin

Slow light systems are particularly attractive for analog signal processing, since their inherent limitation to a delay-bandwidth product of 1 is less critical for analog systems such as those used in microwave photonics. We present here the implementation ...

Partial cognitive relay channel

Masih Nilchian, Vahid Aref

We define partial cognitive relay channel as a two-transmitter, two-receiver interference channel with a relay node such that one of the transmitters is a cognitive transmitter. As a more feasible assumption we assume that the cognitive transmitter has non ...

A Narrowband Multi-Channel 2.4 GHz MEMS-Based Transceiver

Christian Enz

This paper presents a new radio architecture targeting RF transceivers for WSN, WBAN, and biomedical applications. The high miniaturization required by such applications is achieved thanks to the combination of high-Q MEMS devices, such as RF BAW re ...

Digital Compensation of Cross-Modulation Distortion in Software-Defined Radios

Ali H. Sayed

The wideband RF receiver in a software-defined radio (SDR) system suffers from the nonlinear effects caused by the front-end analog processing. In the presence of strong blocker (interference) signals, such nonlinearities introduce severe cross modulation ...

Distributed signal processing for binaural hearing aids

Olivier Roy

Over the last centuries, hearing aids have evolved from crude and bulky horn-shaped instruments to lightweight and almost invisible digital signal processing devices. While most of the research has focused on the design of monaural apparatus, the use of a ...

Signal Processing for Communications

Martin Vetterli, Paolo Prandoni

With a novel, less classical approach to the subject, the authors have written a book with the conviction that signal processing should be taught to be fun. The threatment is therefore less focused on the mathematics and more on the conceptual aspects, the ...
