The spectrum for large sets of -GDDs of type
X. Niu, H. Cao, R. Javadi
In this paper, we completely solve the existence of large sets of -GDDs of type and the existence of a simple -GDD of type .
Non-existence of perfect binary sequences
X. Niu, H. Cao, K. Feng
Binary sequences with lower autocorrelation values have important applications in cryptography and communications. In this paper, we present all possible parameters for binary peri…

X. Lu, X. Niu, H. Cao
A generalized strong external difference family (briefly -GSEDF) was introduced by Paterson and Stinson in 2016. In this paper, we construct s…
