[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。

Abstract: Fourier Transform (FT) is an important signal processing technique that translates time-domain signals to frequency-domain forms. It is widely used in several applications, including 5G ...

MatX is a modern C++ library for numerical computing on NVIDIA GPUs and CPUs. Near-native performance can be achieved while using a simple syntax common in higher-level languages such as Python or ...

We introduce an open-source Python package for the analysis of large-scale electrophysiological data, named SyNCoPy, which stands for Systems Neuroscience Computing in Python. The package includes ...

Kokkos-FFT implements local interfaces between Kokkos and de facto standard FFT libraries, including FFTW, cufft, hipfft (rocfft), and oneMKL. "Local" means not using MPI, or running within a single ...
