📝 Release Notes

🚀 Overview | 概览

This release provides a complete simulation framework for Analog and Digital Communication Systems, developed as part of the Communication Principles Lab at CQUPT.
本版本提供了完整的模拟与数字通信系统仿真框架，涵盖了《通信原理》实验课程的核心内容。

✨ Key Features | 核心特性

• Linear Modulation (AM/DSB/SSB): * Complete implementation of AM, Double Sideband (DSB), and Single Sideband (SSB) modulations.

• Supports both coherent and non-coherent demodulation.

• Frequency Modulation (FM) Analysis:

• Verified Carson's Rule for WBFM bandwidth estimation.

• Demonstrated the Bessel Zero phenomenon at .

• Implemented high-fidelity Hilbert Phase Demodulation.

• Digital Transmission (BPSK):

• Simulated BPSK system with SRRC (Root Raised Cosine) pulse shaping.

• Comparative analysis of spectral leakage between rectangular and roll-off pulses.

🛠️ Verification | 实验验证内容

• Analyzed demodulation performance under different SNR conditions (10dB vs 40dB).
• Verified the impact of carrier phase offset on DSB coherent demodulation.
• Validated Bandpass Filtering (BPF) effects on BPSK signal frequency characteristics.
