FCC Seeks Comments On Asymmetrical HD Radio Sidebands
November 2, 2011 at 4:00 AM (PT)
The FCC has put up for public comment a proposal by iBIQUITY DIGITAL and NPR to allow FM stations to operate with unequal digital sideband power levels. The proposal for what would amount to asymmetrical HD RADIO power levels follows field testing by NPR of technology for reducing the peak-to-average power ratio in digital transmitters, which concluded that "broadcasters are best off maintaining symmetrical sideband levels, but coverage improvements are possible with an increase of only one sideband."
Comment dates will be set once the notice is published in the Federal Register, with comments due 21 days after publication and replies 35 days after publication.
