[导读]GPS L1 C/A信号（1575.42 MHz，BPSK调制，1.023 MHz码率）是软件定义无线电（SDR）入门经典案例。借助RTL-SDR / HackRF / USRP + GNURadio或Python，可完成从原始IQ到NMEA语句的完整处理链路。本文聚焦工程实现要点。 GPS L1 C/A信号（1575.42 MHz，BPSK调制，1.023 MHz码率）是软件 ...

When investigating lightning, focusing not only on the light (the flash) but also on the sound (the thunder) is an effective approach. Thunder is a pressure wave in the atmosphere and carries ...

[导读]在工业设备预测性维护中，振动信号分析是诊断轴承、齿轮、电机等旋转部件故障的核心技术。通过快速傅里叶变换（FFT）将时域振动信号转换为频域频谱，可精准识别设备异常特征频率，实现故障早期预警。本文以滚动轴承为例，解析FFT分析流程与频谱 ...

In modern machine learning workflows, most signal processing tasks rely on Python's SciPy utilities. However, there is no Java library that replicates SciPy's behavior with comparable completeness and ...
