[IRCA] Digital possibility

["Craig Healy" <bubba@xxxxxxxxxxxxxxxxxxxx>]

Bell Labs has a research project to drop the power level of digital
communications such as networking.  Their design is to pick the 1's and 0's
out of a data stream more efficiently.  This means that they will need less
power to pull data out of the noise.  They claim it will take very little
change to do so.

If this could be applied to IBOC, the potential coverage of the digital
portion could be significantly greater without any power increase.  In fact,
the digital sideband power may be able to be decreased to match the current
analog coverage.  From a DX perspective, we may be able to hear more distant
stations digitally than by analog.  It's sort of a paradigm shift in the
hobby, but...

The story is on the Popular Science web site.  http://www.popsci.com/

I would also have to wonder if this could somehow be applied to the DSP
chips in ULRs.  Now THAT would be interesting.
