摘要

本文对通信系统中不同的数字调制方式ASK、FSK和PSK进行了研究。实验是在两种不同条件下进行的。在无噪声的情况下，simulink的仿真结果表明，经过调制解调后，解调后的信号与原始信号大致相同。在有噪声的情况下，需要对信号进行滤波重构。

Research of Digital Communication System

This paper studys ASK, FSK and PSK, which are different digital modulation methods of communication system. The experiments are done under two different conditions. In the situation of no noise, the simulation results of simulink show that after modulation and demodulation, the demodulated signal is roughly the same as the original signal. In the sitution of noise, filter is needed to reconstruct the signal.
