+ * Reed-Solomon coding and decoding
+ * Phil Karn (karn at ka9q.ampr.org) September 1996

+ * This file is derived from the program "new_rs_erasures.c" by Robert
+ * Morelos-Zaragoza (robert at spectra.eng.hawaii.edu) and Hari Thirumoorthy
+ * (harit at spectra.eng.hawaii.edu), Aug 1995
+ *
+ * I've made changes to improve performance, clean up the code and make it
+ * easier to follow. Data is now passed to the encoding and decoding functions
+ * through arguments rather than in global arrays. The decode function returns
+ * the number of corrected symbols, or -1 if the word is uncorrectable.
+ *
+ * This code supports a symbol size from 2 bits up to 16 bits,
+ * implying a block size of 3 2-bit symbols (6 bits) up to 65535
+ * 16-bit symbols (1,048,560 bits). The code parameters are set in rs.h.
+ *
+ * Note that if symbols larger than 8 bits are used, the type of each
+ * data array element switches from unsigned char to unsigned int. The
+ * caller must ensure that elements larger than the symbol range are
+ * not passed to the encoder or decoder.

+           alpha=2 is the primitive element of GF(2**m)
+           HARI's COMMENT: (4/13/94) alpha_to[] can be used as follows:
+                Let @ represent the primitive element commonly called "alpha" that
+           is the root of the primitive polynomial p(x). Then in GF(2^m), for any
+           0 <= i <= 2^m-2,
+                @^i = a(0) + a(1) @ + a(2) @^2 + ... + a(m-1) @^(m-1)
+           where the binary vector (a(0),a(1),a(2),...,a(m-1)) is the representation
+           of the integer "alpha_to[i]" with a(0) being the LSB and a(m-1) the MSB. Thus for
+           example the polynomial representation of @^5 would be given by the binary
+           representation of the integer "alpha_to[5]".
+                           Similarily, index_of[] can be used as follows:
+                As above, let @ represent the primitive element of GF(2^m) that is
+           the root of the primitive polynomial p(x). In order to find the power
+           of @ (alpha) that has the polynomial representation
+                a(0) + a(1) @ + a(2) @^2 + ... + a(m-1) @^(m-1)
+           we consider the integer "i" whose binary representation with a(0) being LSB
+           and a(m-1) MSB is (a(0),a(1),...,a(m-1)) and locate the entry
+           "index_of[i]". Now, @^index_of[i] is that element whose polynomial
+            representation is (a(0),a(1),a(2),...,a(m-1)).
+           NOTE:
+                The element alpha_to[2^m-1] = 0 always signifying that the
+           representation of "@^infinity" = 0 is (0,0,0,...,0).
+                Similarily, the element index_of[0] = A0 always signifying
+           that the power of alpha which has the polynomial representation
+           (0,0,...,0) is "infinity".
