Read this: Closing in on the perfect code
It’s not often in the rarefied world of technological research that an esoteric paper is greeted with scoffing. It’s even rarer that the paper proves in the end to be truly revolutionary. It happened a decade ago at the 1993 IEEE International Conference on Communications in Geneva, Switzerland. Two French electrical engineers, Claude Berrou and Alain Glavieux, made a flabbergasting claim: they had invented a digital coding scheme that could provide virtually error-free communications at data rates and transmitting-power efficiencies well beyond what most experts thought possible. “
The story goes that because of the physical laws of aerodynamics, it is impossible for the bumblebee to fly. Because the bumblebee doesn’t know this, he does it anyway. A couple of French scientists have done the same things with the limits of data correction – thereby theoretically making it possible to use absolute maximum capacity bandwidth with no data loss or errors.
The implications for digital radio are huge. Audio is bandwidth-hungry. Multimedia cellphones have severe data limitations. This could help the convergence project radically. I’ll try and find out more about this and see if I can figure out if the DAB via cellphone signal is actually possible under these new laws of communication.
