In this correspondence, we present a new construction for 64-QAM Golay sequences of length n=2/sup m/ for integer m. The peak envelope power (PEP) of 64-QAM Golay sequences is shown to be bounded byâ€¦ (More)

DES can be regarded as a nonlinear feedback shift register (NLFSR) with input. From this point of view, the tools for pseudo-random sequence analysis are applied to the S-boxes in DES. The propertiesâ€¦ (More)

The Boolean functions of k variables, f(x 1 , x ,...,x ), fall into equivalence classes (or families) when two functions differing only by pe r&tatiof: or complementation of their variables areâ€¦ (More)

A generalized Barker sequence is a finite sequence { ur ] of complex numbers having absolute value 1, and possessing a correlation function C(T) satisfying the constraint IC(r) 1 5 1, 7 # 0. Classesâ€¦ (More)

In this correspondence, we present five new classes of binary sequences of period2 1 with ideal autocorrelation. These sequences, which correspond to new cyclic Hadamard difference sets, were foundâ€¦ (More)

In this correspondence, we present a connection between designing low-correlation zone (LCZ) sequences and the results of correlation of sequences with subfield decompositions presented in a recentâ€¦ (More)
