New wireless devices are often both multi-mode and multi-frequency, operating with a variety of modulations and carrier frequencies simultaneously. Ensuring that system-level specifications are met is difficult because of the sheer number of potential operating states. This requires development of creative solutions for the measurement of broadband, high-dynamic-range signals, both in terms of intentional signals and distortion. Development of measurement techniques that uncover key performance parameters of broadband modulated signals for wireless systems will be the focus of the project. The work will provide a good mix of theoretical development and hands-on experiment in an area of intense commercial growth.
