数字调制解调实验报告 by Yan-anzhi · Pull Request #26 · jwentong/wireless-modulation-experiment

Yan-anzhi · 2026-04-30T10:45:22Z

本次实验完成了数字调制解调系统的基础功能与部分扩展功能，主要包括：

完成 BPSK 调制函数，实现比特 0 -> +1、比特 1 -> -1 的映射，并生成 BPSK 星座图。
完成 QPSK 调制函数，采用 Gray 编码方式将每 2 个比特映射为 1 个复数符号，并生成 QPSK 星座图。
完成 16-QAM 调制函数，采用 I/Q 两路 Gray 编码映射，并进行平均功率归一化，生成 16-QAM 星座图。
完成 BPSK、QPSK 和 16-QAM 的解调函数，能够根据接收符号恢复原始比特序列。
完成 BER 性能测试，生成随机比特序列，经过调制、AWGN 加噪、解调和误码率计算，绘制不同调制方式的 BER vs SNR 对比曲线。
使用自动评分测试验证代码正确性，BPSK、QPSK 和 16-QAM 调制测试均已通过。
