Norm quadratic-residue codes

Introduces a new class of binary linear error-correcting codes, based on the concept of the finite upper half-plane. A norm quadratic-residue code C/sub p/ has p(p-1) coordinate places labeled by ordered pairs (a,b), where p is a prime of the form 4m+1 and a,b /spl isin/ GF(p), b/spl ne/0. Some fundamental properties of C/sub p/ are established.<
