The basic digital modulation methods are amplitude keying (ASK), frequency shift keying (FSK), absolute phase shift keying (PSK), and relative (differential) phase shift keying (DPSK). At the receiving end, the digital baseband signal can be restored by using dry demodulation or non-coherent demodulation. Digital signal transmission methods are divided into baseband transmission and bandpass transmission. However, most channels in practice, such as wireless channels, have rich low frequency components. In order for a digital signal to be transmitted in a band channel, the carrier must be modulated with a digital baseband signal to match the signal to the characteristics of the channel.)
