Constructions of Binary Cross Z-Complementary Pairs With Large CZC Ratio
Hui Zhang, Cuiling Fan, Sihem Mesnager
Cross Z-complementary pairs (CZCPs) are a special kind of Z-complementary pairs (ZCPs) having zero autocorrelation sums around the in-phase position and end-shift position, also ha…
New constructions of -Ary 2-D Z-Complementary Array Pairs
Hui Zhang, Cuiling Fan, Sihem Mesnager
This paper is devoted to sequences and focuses on designing new two-dimensional (2-D) Z-complementary array pairs (ZCAPs) by exploring two promising approaches. A ZCAP is a pair of…
A remark on weaken restricted isometry property in compressed sensing
Hui Zhang
The restricted isometry property (RIP) has become well-known in the compressed sensing community. Recently, a weaken version of RIP was proposed for exact sparse recovery under wea…
On robust width property for Lasso and Dantzig selector
Hui Zhang
Recently, Cahill and Mixon completely characterized the sensing operators in many compressed sensing instances with a robust width property. The proposed property allows uniformly…
New bounds for circulant Johnson-Lindenstrauss embeddings
Hui Zhang, Lizhi Cheng
This paper analyzes circulant Johnson-Lindenstrauss (JL) embeddings which, as an important class of structured random JL embeddings, are formed by randomizing the column signs of a…
