A method for constructing sets of sequences with zero-correlation zone (ZCZ sequences) and sequence sets with low cross correlation is proposed. The method is to use families of short sequences and complete orthogonal sequence sets to derive families of long sequences with desired correlation properties. It is a unification of works of Matsufuji and Torii et al., and there are more choices of p...

This paper describes a constant impedance transmission line pulse system with new measurement capabilities and improved accuracy. The paper enforces a broader look at transmission line pulse (TLP) data, beyond the – curves. Accurate TLP measurements and actual TLP/HBM device data are used to demonstrate effects and HBM/TLP correlation and miscorrelation. Finally, a calibration method and standa...

This paper proposes a new correlation analysis method for nonstationary and energy-limited continual signals, which works out a formula similar to time correlation theory; that is to say when the operator, , meets a certain condition, its auto-correlation property of Fourier transform can be presented by Fourier transform of its energy function, f 2 ) ( t f , revealing its correlation of the Fo...

In this paper, for integers n and e such that e|n and 2 − 1 is a prime, we propose a method of constructing binary low correlation zone (LCZ) sequences of period 2n−1 by using the extended form sequence with the same period. These new LCZ sequences use Legendre sequences as their column sequences.

1. Introduction Suen 8] found a remarkable correlation inequality, giving estimates for the probability that a collection of dependent random indicator variables vanish simultaneously, or in other words, for the probability that none of a collection of dependent events occurs. The present author 4, 3] has found similar inequalities for a much more restricted situation; when applicable, these in...

We propose to quantify the “correlation” inherent in a many-electron (or manyfermion) wavefunction ψ by comparing it to the unique uncorrelated state that has the same 1-particle density operator as does |ψ〉〈ψ|. Electron correlation is of fundamental importance in quantum chemistry and magnetism, but as yet there is no definitive way to quantify it: given the wavefunction ψ(x1, x2, . . . , xN) ...
