In this correspondence, we prove that the complex cross-correlation of a k-ary Sidel'nikov sequence of period q-1 and its constant multiple sequence is upper bounded by radicq+3, where q=pm and hereâ€¦ (More)

We classify some p/sup k/-ary (p prime, k integer) generalized m-sequences and generalized Gordon-Mills-Welch (GMW) sequences of period p/sup 2k/-1 over a residue class ring R=GF(p)[/spl xi/]/(/splâ€¦ (More)

Adaptive-array beamforming achieves high resolution and sidelobe suppression by producing sharp nulls in the adaptive beampattern. Large-aperture sonar arrays with many elements have small resolutionâ€¦ (More)

Let p be a prime, q = pm and Fq be the finite field with q elements. In this paper, we will consider q-ary sequences of period qn âˆ’ 1 for q > 2 and study their various balance properties:â€¦ (More)

Let p be an odd prime, q be a divisor of p - 1 and mu be a primitive root mod p. A g-ary PRS (power residue sequence) of period p is defined as s(n) = k if n isin Ck where Ck = {muqt+k|t =â€¦ (More)

We review prime n-square sequences of length pn which is originally defined by Ding and Helleseth in 1998, where p is an odd prime and n is a positive integer. In this paper, we determine the linearâ€¦ (More)

We consider a design of quasicyclic LDPC codes which have irregular column weights. We derive bit-oriented bound and parity-oriented bound on the minimum distances of irregular quasicyclic codesâ€¦ (More)
