Reed-Solomon codes are a form of FEC (Forward Error Correction).|
They make sense for communications channels that don't have
a way for the receiver to ask for a re-transmission (such as
Reed-Solomon codes are used on many digital formats. One of
the first uses of RS coding were the Voyager 1 and 2 spacecraft
launched in 1977.
Then came audio CD in 1980 (I bought my first CD player in 1983).
It uses a RS(28,24) and a RS(32,28) code.
Other uses are DSL and Wimax (although you don't see much Wimax
In current standards, RS codes are now being replaced with
more complex BCH (Bose, Chaudhuri, Hocquenghem) codes.
