Turbo Codes Promise Better Wireless Transmission

captain igor writes "IEEE is running a story about two French professors that have created a new class of encoding, called 'Turbo Codes,' that will allow engineers to pass almost twice as much data through a given communications channel, or equivalently, the same amount of data at half the power. The new codes allow the Shannon Limit (the theoretical maximum capacity of a channel) to be approached to, currently, within .5 dB. Scientists hope that this breakthrough will revolutionize wireless communications, especially with the coming reclamation of large swaths of the EM spectrum." As the article points out, such codes are in use now, but seem poised for much wider implementation.

    Finally, by forcing more air into the cylinders than ordinary air pressure would allow, we will be able to achieve more efficient combustion, which will in turn allow us to transmit more data using radio frequencies. ...Don't you just hate it when terminology gets mis-applied to stuff it has nothing to do with?

    Dang it, this software isn't made out of platinum, either.

    Like the article says, these codes were introduced in 1993.

    Ahh, that would explain the "Turbo" thing: It comes from the era of Borland compilers and 486 clone boxes. If it were invented today, it would surely be called something like "iCodes".

    Yea, I thought that was odd. When I worked at Motorola about 4 years ago we had a turbo encoder/decoder in a prototype of a 3G cellphone.

    Wonder how long until the story about a revolutionary new compression scheme called LZW hits the frontpage?

    "much as when, in a crowded pub, you have to shout for a beer several times"

    I was wondering when they would get to the practical applications.

    Yeah, I read about that new LZW thing the other day. I just hope it doesn't have patent problems.
