 ARCES Researchers possess high level competences in several fields related to Information and Communication Technologies such as: Semiconductor Devices Physics, IC design, Signal Processing and Algorithms, Non Linear Control, Communications Techniques and Systems, Bio-Electronics, Geomatics, Navigation Systems Control, Computer Vision, Applied Mathematics and Geometry.
The main research areas, corresponding to fundamental enabling technologies for ICT, are listed below:
- CMOS sensors and signal-processing architectures
- Computer vision and image-processing systems
- Advanced wireless communication systems
- Satellite systems for navigation control and real-time kinematic
- Device simulation and quantum computing
- Circuits, systems and algorithms for signal processing
Research programs 1 to 4 exist since ARCES inception, and embody the research program on electronic systems defined in the original proposal submitted to, and approved by, the Ministry of Education, University and Research. The fifth program represents instead a traditional research area of the Electronics group and, while not being part of the above research program, has gained recognition at a later time as an additional research area to be pursued within the Center. Of course, this activity has not been funded with the resources made available by MIUR. Program 6 was originally part of the research area 3 and has recently spun off as an independent program.
RP1 addresses the development of CMOS sensors and biosensors, reconfigurable signal-processing architectures and three-dimensional (3D) integration. The largest part of this activity, excluding biosensors, is heavily supported by ST Microelectronics, and is being carried out within a joint STM-ARCES lab referred to as STAR. The partnership with STM is governed by a Scientific Committee, which typically meets bi-annually, nominates the lab Director and approves the research programs proposed by him.
RP2 addresses several problems connected with computer vision and image processing, which range from theoretical aspects, i.e. the investigation on qualitative shape descriptors termed "size functions", to the development of software systems for video-surveillance, traffic monitoring, behavior analysis and hardware terminals (tablet PCs) equipped with on-board sensors to manage system resources and to support context-aware applications. RP3 carries out research work in the area of wireless communication systems, which range from the identification of critical subsystems of terrestrial and satellite UMTS, with the aim of devising innovative solutions at algorithmic and system level, to the investigation of future IP-based, 4G communication systems able to provide very large data rates.
RP3 also includes the development of highly-integrated, low-cost, CMOS transceivers addressing the issue of multi-standard terminals and reconfigurability at the hardware level.
RP4 aims at implementing satellite-based air and sea navigation-control systems and real-time kinematic systems based on a network of continuously-operating reference stations. This program includes the development of an instrumental approach and landing system for small aircrafts based on the use of GPS and ground stations for error detection and transmission to the landing aircraft; a control system of unmanned aerial vehicles, and a management system for ground-traffic control in airport areas.
RP5 addresses various problems related with modeling, simulation and characterization of semiconductor devices, including, but not limited to, nanometer-size silicon devices, such as double-gate and nanowire FETs, carbon nanotubes and smart-power technologies. The investigation on novel quantum gates that could become suitable candidates for quantum computation is also part of this activity.
RP6 addresses non-linear dynamics methodologies for the solution of advanced signal-processing problems, such as mitigating electromagnetic interference (EMI) in microprocessor systems, identifying simple design guidelines to reduce the IC susceptibility to EMI, developing novel CDMA modulation techniques with reduced bandwidth for a given bit error rate, generating high-speed true random numbers, and developing innovative chaos-based cryptographic techniques. Finally, an activity on the analysis of ultrasonic signals and interpretation of biological images is part of this work program.
