Block or Convolutional?
Many debates are out there in the literature on which
coding technique is better.
It really depends on the application.
For an AWGN channel convolutional codes are
preferable. They approach asymptotic gains at
relatively high BER (10
) (e.g sat TV).
For low BER requirements RS codes are better
because they achieve higher asymptotic gains at
lower BER (10
Concatenation of RS and convolutional codes produce
very strong error correcting capabilities.
