| Abstract: | HD Radio is the American digital sound broadcasting standard in AM and FM band which FCC has approved. There are more than 60 testing programs and more than 1500 transmitting stations in the United States. This technology, basing on IBOC, can provide high quality digital sound broadcasting and data business, using existing analog broadcasting channels, without prejudice to the existing analog broadcasting. In order to find out transmission and coverage performance of the digitalization of FM radio in HD Rad... |
