ITTC Project


An Investigation of Software Radio Techniques

Project Award Date: 0000-00-00



Description

The May 1995 issue of the IEEE Communications Magazine is devoted to the subject of software radio. The lead article begins with the following observation: "We are poised on the threshold of another revolution in radio systems engineering. Throughout the '70s and '80s radio systems migrated from analog to digital in almost every respect from system control to source and channel coding to hardware technology. And now the software radio revolution extends these horizons by liberating radio based services from chronic dependency on hard wired characteristics, including frequency band, channel bandwidth, and channel coding." The software radio architecture centers on the use of wideband A/D and D/A converters as close to the antenna as possible, with as much radio functionality as possible defined in software. The resulting software-defined radio (or "software radio") extends the evolution of programmable hardware, increasing flexibility via increased programmability. Our research role in this area builds out of our expertise in both digital signal processing rapid prototyping and radio system design. The former supported by the U. S. Air Force and the latter supported by ARPA. We intend to investigate the implementation of a totally configurable radio system using off-the-shelf DSP microprocessors and field programmable gate arrays. Our initial effort will be to capture the rf signal after the first rf amplifier stage using high speed bandpass sampling techniques. Parallel C40 DSP processor will then implement all of the radio functions.


Investigators




Partner with ITTC

The Information and Telecommunication Technology Center at the University of Kansas has developed several assistance policies that enhance interactions between the Center and local, Kansas, or national companies. 

ITTC assistance includes initial free consulting (normally one to five hours). If additional support is needed, ITTC will offer one of the following approaches: 

Sponsored Research Agreement

Individuals and organizations can enter into agreements with KUCR/ITTC and provide funds for sponsored research to be performed at ITTC with the assistance of faculty, staff and students.

Licensing and Royalty/Equity Agreement

An ITTC goal is the development of investment-grade technologies for transfer to, and marketing by, local, Kansas, and national businesses. To enhance this process, the Center has developed flexible policies that allow for licensing, royalty, and equity arrangements to meet both the needs of ITTC and the company.

Commercialization Development

Companies with a technology need that can be satisfied with ITTC's resources can look to us for assistance. We can develop a relationship with interested partners that will provide for the development of a technology suited for commercialization.

ITTC Resource Access

ITTC resources, including computers and software systems, may be made available to Kansas companies in accordance with the Center's mission and applicable Regents and University policies.
