High Definition Radio is Here 389
nfranzen submits this story/advertisement: "Yesterday, I had the opportunity to buy the first High Definition (HD) Radio in the United States. HD Radio, invented by iBiquity Digital, adds a digital channel to the sidebands of an existing analog FM signal. The technology is still pretty new, but I can tell you first-hand that listening to my favorite local FM station in HD sounds just like I am listening to a CD. Well, except for the commercials (grin). Here are some links to local TV news coverage and a news release for more info. HD receivers will hit the open market following the Consumer Electronics Show next week in Vegas." We had an old story about the FCC approving these digital broadcasts in the FM radio bands.

BTW, digital cellular is popular with the carriers not only because of spectrum efficiency, but because of superior link budgeting with lower output power. The range is actually better on digital cellular protocols (whether TDMA or CDMA) than FDMA/AMPS. The reason why your user experience is better with analog is that there is so much more analog stuff deployed. This is likely to change (not exactly a ton of AMPS equipment is still getting deployed).
Data compression reduces signal bandwidth. And reduced bandwidth means less noise in the band where the signal is, and also means that the signal, since it is less wide, is stronger. This translates to better S/N and thus better link budget. Also, there are things like coding gain which you can't make use of with analog transmissions.
I don't know how the HD FM divides output power/spectrum to the subcarriers. But it is likely that you can still get a perfectly clear digital signal when the analog FM station would be unlistenable.
analog vs. digital (Score:5, Informative)
With AMPS, as the signal gets weaker, the audio noise floor comes up, and you get wideband static on the signal. Wideband static is fairly benign, in that humans aren't as offended by it (since it sounds like the surf). The user of the phone knows he is getting out of range well before the call drops, and so usually can terminate the call gracefully.
With digital, you get no real degradation of the signal so long as the channel bit error rate is less than the channel's error recovery capability. But when the BER gets above that threshold, then the quality drops dramatically. Moreover, the loss of quality is expressed as garbled vocoder output (I've always described it as "watery" - it sounds like you have water in your ears), or as complete failures of the vocoder (dropouts). Those are VERY offensive to the ear.
Also, the difference between a signal level that gives you a fully correctable BER and a signal level that gives you a BER bad enough the phone drops is almost nil - so just changing position can drop the call without warning.
Personally, if the phone makers would tie the received signal strength indicator (RSSI) into a variable noise generator, so that as the RSSI fell you started to get static, I think most people wouldn't bitch so badly about dropped calls.
There is also the problem that the usual vocoders for phone use are compressing the crap out of the signal - taking a 64 kb/second audio stream down to less than 4kb/sec. VSELP, IMBE and AMBE all do OK when fed voice in isolation, but put in any background noise and they get "confused" - they start making poor choices about the vectors they encode, and what comes out the other end is pretty rocky.
I had great fun feeding the first few seconds of Kansas's "Carry On Wayward Son" into an APCO-25 IMBE vocoder. While there is nothing but voice there, it is a chorus, and the poor vocoder just couldn't figure out what was going on.

For those of you who are broadcasting contemporary formats, the codec removes sibilance unnaturally, changes the timber of symbols and makes back up vocals strident. This is not CD-quality by a long shot. In fact, during my listening test I found that our station's plain old analog signal sounded better than the 96kb/s codec."

Or alternatively you could go with satelite radio, but that has subscription costs, because they don't have commercials, but the subscription costs are pretty high, because they have to pay those same royalties, because RIAA perceives that they are losing money to our hard drives.
