Let {a1} and {ad1} be two maximal linear sequences of period pn − 1. The cross-correlation function is defined by Cd(t) = for t = 0, t…pn − 2, where ζ = exp(2π 1p). We find some new general results… Expand

In this paper we first introduce a new generalized cyclotomy of order 2 with respect tope11···pett, then we calculate the new cyclotomic numbers of order 2. Some applications of the new cyclotomy in… Expand

For a prime q and an integer j/spl les/q, the code C(q,j) is a class of low-density parity-check (LDPC) codes from array codes which has a nice algebraic structure.Expand
