[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 ...

网上有些博主写的信号处理文章也不错，但是我觉得缺少了信号与系统的数学之美，而且整体给的说服力也不够。（那我就准备启动重写计划） 当采样点数从 增加到 、 时，正弦信号峰值基本不变，而频域每个 bin 里的噪声功率大约每增加 10 倍点数下降 10 dB。

I have been conducting various video analyses using MediaPipe and Python. A book I read recently described a method for calculating heart rate from color changes in the face or hands within a video, ...

[导读]在生物医学信号处理领域，MATLAB凭借其强大的快速傅里叶变换(FFT)功能，成为分析心电信号(ECG)和脑电信号(EEG)频域特性的核心工具。通过FFT算法，研究者能够将时域信号转换为频域分布，精准识别信号中的关键频率成分，为疾病诊断和生理机制研究提供 ...
