-/* This program is an encoder/decoder for Reed-Solomon codes. Encoding is in
- systematic form, decoding via the Berlekamp iterative algorithm.
- In the present form , the constants mm, nn, tt, and kk=nn-2tt must be
- specified (the double letters are used simply to avoid clashes with
- other n,k,t used in other programs into which this was incorporated!)
- Also, the irreducible polynomial used to generate GF(2**mm) must also be
- entered -- these can be found in Lin and Costello, and also Clark and Cain.
-
- The representation of the elements of GF(2**m) is either in index form,
- where the number is the power of the primitive element alpha, which is
- convenient for multiplication (add the powers modulo 2**m-1) or in
- polynomial form, where the bits represent the coefficients of the
- polynomial representation of the number, which is the most convenient form
- for addition. The two forms are swapped between via lookup tables.
- This leads to fairly messy looking expressions, but unfortunately, there
- is no easy alternative when working with Galois arithmetic.
-
- The code is not written in the most elegant way, but to the best
- of my knowledge, (no absolute guarantees!), it works.
- However, when including it into a simulation program, you may want to do
- some conversion of global variables (used here because I am lazy!) to
- local variables where appropriate, and passing parameters (eg array
- addresses) to the functions may be a sensible move to reduce the number
- of global variables and thus decrease the chance of a bug being introduced.
-
- This program does not handle erasures at present, but should not be hard
- to adapt to do this, as it is just an adjustment to the Berlekamp-Massey
- algorithm. It also does not attempt to decode past the BCH bound -- see
- Blahut "Theory and practice of error control codes" for how to do this.
-
- Simon Rockliff, University of Adelaide 21/9/89
-
- 26/6/91 Slight modifications to remove a compiler dependent bug which hadn't
- previously surfaced. A few extra comments added for clarity.
- Appears to all work fine, ready for posting to net!

- This program may be freely modified and/or given to whoever wants it.
- A condition of such distribution is that the author's contribution be
- acknowledged by his name being left in the comments heading the program,
