Some new almost difference sets via finite fields

ACM Communications in Computer Algebra, 2015
Several investigations on antenna arrays focus on the “thinning” problem wherein one would like to reduce the number of array elements with respect to the original filled layouts. The rationale to do so is to economize costs, weight, consumption of power etc.

MIMO radar array thinning using almost difference sets

2016 10th European Conference on Antennas and Propagation (EuCAP), 2016
In this paper, minimum redundancy multiple-input multiple-output (MR-MIMO) arrays - a class of thinned antenna arrays - are discussed. The concepts of MR-MIMO array design and almost difference sets (ADSs) are introduced, and an analytical method based on ADSs is proposed for MR-MIMO array designs.

MIMO radar array thinning optimization exploiting almost difference sets

Optik, 2016
Abstract Thinning techniques based on almost difference sets (ADSs) are presented to design MIMO radar antenna arrays with low peak sidelobe levels (PSLs). The standard ADS approach allows one to analytically determine the element locations of the transmitting and receiving arrays and estimate the upper bound of the radiation pattern sidelobes of ...

Construction of binary almost perfect sequences based on extended cyclic difference sets

1998 International Zurich Seminar on Broadband Communications. Accessing, Transmission, Networking. Proceedings (Cat. No.98TH8277), 2002
Sequences with noise-like characteristics are required for symbol synchronization, signal detection, signal estimation, spectrum spreading and secrecy coding. Periodic binary sequences exhibiting zero out-of-phase autocorrelation except one value in the middle are studied here. They are based mainly on cyclic difference sets D with parameters (v,k,/spl
