Abstract: This paper presents a method for constructing optimal frequency hopping patterns with ideal autocorrelation and cross-correlation properties based on algebraic Costas arrays. A ...

Abstract: This paper introduces a two-dimensional orthogonal pattern division multiple access (OPDMA) communication method based on optimal frequency hopping patterns and explores the use of ...

For the first time, researchers have shown that self-assembled phosphorus chains can host genuinely one-dimensional electron behavior. Using advanced imaging and spectroscopy techniques, they ...
