New Matrices with Good Auto and Cross-Correlation
نویسندگان
چکیده
Large sets of matrices with good auto and cross-correlation are rare. We present two such constructions, and a method of extending them, by a simple process of interlacing arrays from a well prepared family of arrays with good autocorrelation and with good cross-correlation between any two arrays in the family. These matrices can be applied to digital watermarking of images.

Families of Matrices with Good Auto and Cross-Correlation
We construct a family of p-1 square p% p matrices (p is any prime) whose periodic cross-correlation values are uniformly –p,0,+p between all pairs of the matrices in the family. For every one of the matrices in the family, all the off -peak autocorrelation values are –p and 0, while the single peak valu e is p(p-1). For p=127 (where the values –p,0,+p are below 1% of the size p of the matrices)...
متن کاملAn Analysis of the Bias-Property of the Sample Auto-Correlation Matrices of Doubly Selective Fading Channels for OFDM Systems
In this paper, by assuming equiprobable centrosymmetric constellation adopted for modulation, the mathematic expectation of the sample auto-correlation matrix obtained through the least-squared channel estimation is derived under a rigorous model of the doubly selective fading channel for orthogonal frequency division multiplexing (OFDM) systems. Based on the derived expectation, the bias-prope...
متن کاملComputationally Efficient 2D DOA Estimation with Uniform Rectangular Array in Low-Grazing Angle
In this paper, we propose a computationally efficient spatial differencing matrix set (SDMS) method for two-dimensional direction of arrival (2D DOA) estimation with uniform rectangular arrays (URAs) in a low-grazing angle (LGA) condition. By rearranging the auto-correlation and cross-correlation matrices in turn among different subarrays, the SDMS method can estimate the two parameters indepen...
متن کاملApplication of Nega-cyclic Matrices to Generate Spreading Sequences
In the paper, we present a new class of orthogonal bipolar spreading sequences designed based on Goethals-Seidel construction with negacyclic matrices. The sequences can be designed for any length equal to 4 (mod 8), and possess good correlation properties. In particular, their aperiodic autocorrelation characteristics are very good. That can be traded off for improvement in the crosscorrelatio...
متن کاملOn cross-correlation properties of S-boxes and their design using semi-bent functions
In this paper, several methods for constructing substitution boxes (S-boxes) with good cross-correlation properties are proposed. We firstly analyze the cross-correlation properties of bent functions and derive a sufficient condition that the absolute indicator f ,g of two bent functions f and g achieve its lowest possible value 2 n/2. More precisely, it is sufficient that f + g is also a bent ...
