Receivers for Interference-Resistant Wireless Systems
As demand for wireless services increases, wireless systems need to be less vulnerable to interference in a dynamic and crowded radio frequency (RF) environment. Radio receivers form the last line of defense against interference. Amal El-Ghazaly and Alyosha C. Molnar, Electrical and Computer Engineering, are developing a new circuit architecture that will enable receivers to operate across a large portion of the wireless spectrum while adaptively suppressing interference.
This research integrates signal processing and algorithm development, circuit design and optimization, and RF-component design and tuning to create a new class of radio receivers able to identify, adapt to, and suppress interference while working within a broad frequency range. Interference may change as a function of time and location; therefore, as part of this project, researchers will develop an algorithm to guide a receiver’s response to multiple sources of interference.
Technology developed through this research has the potential to significantly enhance adaptive interference mitigation and improve the robustness of future wireless systems. This project will also educate and train engineers, at both the graduate and undergraduate level, to think holistically about the components and operation of wireless systems and to establish robust receivers for the future.
