b = 1. The index set I must be of the form I = A [ B [ C where A = f1g B = fz + 1 j z 2 C0; z + 1 2 C0g and C = f0z j z 2 C1; z + 1 2 C1g: Observe that these three sets are pairwise-disjoint. Therefore, The other cases can be treated similarly. ACKNOWLEDGMENT The authors wish to thank the anonymous referee for careful review of the original manuscript and helpful comments.

Abstract—In this correspondence, a new class of pseudonoise sequences over GF (), based on Gordon–Mills–Welch (GMW) sequences, is constructed. The sequences have the property that, in a specified zone, the out-of-phase autocorrelation and cross-correlation values are all equal to 1. Such sequences with low correlation zone (LCZ) are suitable for approximately synchronized code-division multiple-access (CDMA) system.

On the binary sequences with high GF(2) linear complexities and low GF(p) linear complexities

Klapper [1] showed that there are binary sequences of period q − 1(q is a prime power p, p is an odd prime) with the maximal possible linear complexity q−1 when considered as sequences over GF (2), while the sequences have very low linear complexities when considered as sequences over GF (p). This suggests that the binary sequences with high GF (2) linear complexities and low GF (p) linear comp...

Efficient implementation of low time complexity and pipelined bit-parallel polynomial basis multiplier over binary finite fields

This paper presents two efficient implementations of fast and pipelined bit-parallel polynomial basis multipliers over GF (2m) by irreducible pentanomials and trinomials. The architecture of the first multiplier is based on a parallel and independent computation of powers of the polynomial variable. In the second structure only even powers of the polynomial variable are used. The par...

New designs for signal sets with low cross correlation, balance property, and largelinear span: GF(p) case

New designs for families of sequences over GF ( ) with low cross correlation, balance property, and large linear span are presented. The key idea of the new designs is to use short -ary sequences of period with the two-level autocorrelation function together with the interleaved structure to construct a set of long sequences with the desired properties. The resulting sequences are interleaved s...

New construction of M -ary sequence families with low correlation from the structure of Sidelnikov sequences

The main topics of this paper are the structure of Sidelnikov sequences and new construction of M ary sequence families from the structure. For prime p and a positive integer m, it is shown that M -ary Sidelnikov sequences of period p − 1, if M | pm − 1, can be equivalently generated by the operation of elements in a finite field GF(p), including a p-ary m-sequence. The equivalent representatio...
