The CRC is working on two major enhancements to radio signal processing.
First, Software Defined Radio (SDR) embeds functions such as filtering, coding, and modualtion in a software system that can be altered independently of any hardware platform. The resulting radio can be updated and upgraded even after it is on the market, offering major benefits to manufacturers, operators and consumers. Besides improving the interiperability between equipment used in the military, public safety, and commercial sectors, this technology can reduce the sheer number of radios that users need in the field. Other areas that rely heavily on signal processing and embedded computer systems, such as automotive, avionics, or robotics, are also looking closely at the concepts developed as part of SDR.
Secondly, Cognitive Radio represents protocols that optimize a wireless communications device's use of the radio-frequency spectrum, while minimizing its interference with other devices. This capability makes it possible to adapt and device to current spectrum conditions in real time, providing regulators, licensees and the general public with more flexible, efficient and comprehensive access to this resource. This technology identifies any nearby spectrum use, then changes the frequency, adjusts output power, or alters transmission parameters and characteristics. The approach can significantly increase data throughput and link range without the need for additional bandwidth or transmit power, Cognitive radio also offers a balanced solution to spectrum crowding, assigning priority use to the spectrum owner while allowing others to share unused portions of the spectrum.
