Description

This issue of Microelectronics TOE covers recent developments in cognitive radio technologies. Innovations profiled include cognitive radio network with interference mitigation by xG Technology Inc., wideband RF front-end for cognitive radio systems by Aviacomm, intelligent algorithm for opportunistic spectrum utilization by Cognitive Radio Technologies LLC, and wireless signals-based home monitoring system by Cognitive Systems Corp.

The Microelectronics TechVision Opportunity Engine (TOE) captures global electronics-related innovations and developments on a weekly basis. Developments are centred on electronics attributed by low power and cost, smaller size, better viewing, display and interface facilities, wireless connectivity, higher memory capacity, flexibility and wearables. Research focus themes include small footprint lightweight devices (CNTs, graphene), smart monitoring and control (touch and haptics), energy efficiency (LEDs, OLEDs, power and thermal management, energy harvesting), and high speed and improved conductivity devices (SiC, GaN, GaAs).

Miniaturization, a move toward lower power consumption, and the need for enhanced features are driving innovations in the electronics sector. Technology focus areas include semiconductor manufacturing and design, flexible electronics, 3D integration/IC, MEMS and NEMS, solid state lighting, advanced displays, nanoelectronics, wearable electronics, brain computer interface, advanced displays, near field communication, and next generation data storage or memory.

Keywords: Cognitive radio technology, wireless communication, dynamic spectrum access, digital signal processor
