Error correcting codes, Cassini & wireless 3G

phil — 7/5/2004 4:07:29 PM (archived)

Amazingly, yet again mathematical advances in data transmission and error correcting codes have enabled a richer data set from Cassini and also provide commercial wireless applications. I worked on this stuff way back in the late 70s when the early Reed-Solomon codes were first applied to disk storage devices for mainframe computers.

This latest stuff was invented by Alain Glavieux and Claude Berrou, at the Ecole Nationale SupÃ©rieure des TÃ©lÃ©communications de Bretagne in Brest. These indecipherable alien names give some credence to the idea that we have stolen technology from space aliens.

        good point re wear-&-tear of gimbals - Daniel - 7/6/2004 6:22:43 PM
        
        Cost is always a factor - Larry J - 7/6/2004 6:48:07 PM
        
        at least there's a lot of built-in redundancy - Daniel - 7/6/2004 7:07:40 PM
        
        There may be another consideration - Larry J - 7/6/2004 9:29:34 PM
