基于SystemView的奈奎斯特第一准则的验证与分析

Verification and analysis of the first principle of Nyquist based on SystemView

本文阐述了奈奎斯特第一准则的基本原理,并使用SystemView软件对数字基带系统进行仿真设计。我们修改信道噪声和基带信号的码元传播速率,并观察比较接收波形和发送波形,直观看到噪声和码间干扰对数字基带系统的影响,同时验证了奈奎斯特第一准则。

This paper expounds the first principle of Nyquist, and uses SystemView software to simulate the digital baseband system. We modify the chip rate of channel noise and baseband signal, and compare the sending waveforms and receiving waveforms in analysis window of SystemView. The waveforms show the effort of noise and intersymbol interference on the digital baseband system directly, and verify the first principle of Nyquist.
