New Ternary and Quaternary Sequences with Two-Level Autocorrelation
"... Pseudorandom sequences with good correlation properties are widely used in communications and cryptography. The search of new sequences with two-level autocorrelation has been a very interesting problem for decades. In 2002, Gong and Golomb proposed the iterative decimation-Hadamard transform (DHT) ..."

The decimation-Hadamard transform of two-level autocorrelation sequences
- IEEE Trans. Inform. Theory
, 2002
"... Abstract—A new method to study and search for two-level autocorrelation sequences for both binary and nonbinary cases is developed. This method iteratively applies two operations: deci-mation and the Hadamard transform based on general orthogonal functions, referred to as the decimation-Hadamard tra ..."

GENERALIZED P-ARY SEQUENCES WITH TWO-LEVEL AUTOCORRELATION
"... In this paper, we find a family of-ary sequences with ideal two-level autocorrelation with symbols in the finite field. The proposed family may be considered as a generalization of the well-known nonbinary sequences introduced by Helleseth and Gong. Using the constructed sequences and-sequences, we ..."

Realizations of Decimation Hadamard Transform for Special Classes of Binary Sequences with Two-level Autocorrelation
"... In an effort to search for a new binary two-level autocorrelation sequence, the decimation-Hadamard transform (DHT) based on special classes of known binary sequences with two-level autocorrelation is investigated. It is theoretically proved that some realizations of a binary generalized Gordon-Mill ..."

New Nonbinary Sequences With Ideal Two-Level Autocorrelation Function
, 2001
"... We find new families of nonbinary sequences of period p n 1 with symbols from a finite field F p for any p 3. The sequences have two-level ideal autocorrelation functions and are generalizations of recently found ternary sequences with ideal autocorrelation. Difference sets with parameters ( p n 1 ..."

How much should we trust differences-in-differences estimates?
, 2003
"... Most papers that employ Differences-in-Differences estimation (DD) use many years of data and focus on serially correlated outcomes but ignore that the resulting standard errors are inconsistent. To illustrate the severity of this issue, we randomly generate placebo laws in state-level data on femal ..."

Two corrections based on asymptotic approximation of the variance-covariance matrix work well for moderate numbers of states and one correction that collapses the time series information into a “pre” and “post
Hardware Implementations of Multi-output Welch-Gong Ciphers
"... The WG family of ciphers provides keystreams with mathematically proven randomness properties such as ideal two-level autocorrelation, balance, long period, ideal tuple distribution, and high and exact linear complexity. In this paper, we extend the mathematical analysis of WG family of ciphers to m ..."
