这篇笔记就是从零搭起一个 可验证、可调试、可扩展 的数字调制解调误码率仿真框架，不依赖 Simulink 或商用工具链，纯 Python + NumPy + SciPy 实现，每一步都对应通信教科书里的公式，每个参数都有物理意义，每条曲线都能回溯到香农极限的边界。

This repository contains the implementation of a Quadrature Phase Shift Keying(QPSK) system along with a AWGN channel on Spartan-7 Boolean board, along with its simulation using Python. The project ...

swap any modulation scheme for any other with a one-line change, toggle FEC on/off and measure the resulting coding gain in dB, visualize constellations before and after the channel, reproduce every ...
