NAB White Paper: On-Channel repeater IMPLEMENTATION for HD radio coverage improvement

by Richard Redmond

This paper will be a discussion of the key considerations one needs to evaluate when developing implementation plans for enhanced HD Radio coverage using “on-channel” repeaters or gap fillers. We will examine the implications, challenges and limitations of receiving a HD Radio signal off the air, and repeating the digital only portion on the same channel. There will be a review of antenna isolation required, practical power levels, the benefits and limitations of adaptive echo cancellation and impact on receiver performance. This presentation will explore space planning, power levels and the ongoing costs. This discussion is based on the real world experience with similar projects and networks Harris has been involved with around the world.
