WebOct 1, 2003 · Primitive idempotents and generator polynomials of some minimal cyclic codes of length pnqm. Let p, q and l be distinct odd primes such that l is a primitive root modulo pn as well as modulo qm with g.c.d. (φ (p), φ (q)) so that the complete set of 2mn + m + n + 1 primitive idempotents of the minimal cyclic codes of length pnqm over GF (l ... WebIf there is a codeword of weight 1, the associated code polynomial is Xm, for some 0 m n 1. Since the code is cyclic, it follows that 1 is also a code polynomial. But then the code is trivial (every word is a codeword), and g(X) = 1, contradicting the hypothesis. If there is a codeword of weight 2, the associated code polynomial is Xm+ Xl for ... iran contemporary history
