Abstract: This paper addresses the critical issues of correlation loss and scalloping loss in traditional PMF-FFT algorithm for spread spectrum signal acquisition. An optimized method combining window ...

Consider $A$ and $B$; they are arrays, and $P$ is an array of the same length as $B$. For any $0\leq k < \text{len}(A)$, we want to efficiently calculate: $$ \text ...

Abstract: This paper presents a novel algorithm for active vibration control (AVC), termed Wavelet Packet Transform Based FXLMS (WPT-FXLMS) algorithm. The proposed algorithm addresses the limitations ...

The positioning, navigation, and timing (PNT) information is fundamental to modern information systems. Over the years, people have invented many navigation systems to get PNT information, whereas ...

Dec. 26, 2025 A new microchip-sized device could dramatically accelerate the future of quantum computing. It controls laser frequencies with extreme precision while using far less power than today’s ...
