Abstract
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.
