Addressable HD Radio Receivers (“Smart Radio”) Project
Developed requirements and a proof of concept for a “smart” digital radio receiver that allows the user to create a customizable listening experience. HD Radio broadcast technology can be used to send audio content, either program material or commercials that is “pre-stored” in the receiver. Time slots in the live broadcast can be replaced with pre-stored content depending on user selection.

VHF/UHF Antennas for Integration in Mobile Devices
Designed and built prototype small antenna systems suitable for integration into a cell phone (or similar device) which operates over FM band (88-108 MHz) and TV band (54-88 MHz, 174-216 MHz, 470-698 MHz) frequencies, and suitable for reception of FM radio (analog and/or HD Radio digital for FM band) and ATSC mobile digital TV (DTV) signals.

AM Low-rate Data Service Using IBOC Subcarriers
Investigated and developed a proof of concept for low-rate data service for AM radio stations. The service would utilize a small number of IBOC subcarriers to provide a data capability similar to RDS for FM (but no digital audio). An IBOC receiver would be required to access this new data service.
