Broadcast AM and FM Radio is the last major communications medium to experience the transition from analog to digital. HD Radio's IBOC technology allows broadcasters to transition using the same analog channel allocation for the new digital/analog hybrid signal. Thousands of radio stations are upgrading to digital HD Radio technology. Approximately one new HD Radio broadcaster goes on the air each day, reaching every major U.S. city and 60% of all listeners. By 2008, more than 90% of the U.S. population will be reached by HD Radio broadcasters. This presentation will describe the key communications design features of this technology. See


Dr. Kroeger is the primary inventor of HD Radio In-Band On-Channel (IBOC) technology. He previously served as Chief Scientist for USADR Corp., Westinghouse Wireless Solutions Company, and Westinghouse Communications Division.
