ITTC Project


Continuous-band OFDM System for High-Speed Optical Transmission

Project Award Date: 07-15-2008



Description

Orthogonal frequency-domain multiplexing (OFDM) has been applied to optical transmission systems to increase the optical bandwidth efficiency and improve the tolerance to performance degradation effects such as chromatic dispersion and polarization mode dispersion. Instead of using analog oscillators and mixers, OFDM transmitters and receivers heavily rely on high-speed digital signal processing and A/D-D/A conversion. OFDM systems operation at 20 Gb/s has been demonstrated and further increasing the data rate depends on advances in high-speed D/A conversion electronics. ITTC researchers will investigate a novel coherent band-combining technique to enhance the capability of OFDM systems. This may potentially allow a much higher transmission data rate than current systems provide. It will also make the transmission data rate flexible without sacrificing the bandwidth efficiency.

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.
