Digital Microwave Communication
Microwave is a kind of electromagnetic wave. In a broad sense, the microwave frequency range is from 300 MHz to 300 GHz. But In microwave communication, the frequency range is generally from 3 GHz to 30 GHz.
Concept of Digital Microwave Communication
Digital microwave communication is a way of transmitting digital information in atmosphere through microwave or radio frequency (RF).
Microwave communication refers to the communication that use microwave as carrier.
Digital microwave communication refers to the microwave communication that adopts the digital modulation.
The baseband signal is modulated to intermediate frequency (IF) first . Then the intermediate frequency is converted into the microwave frequency.
The baseband signal can also be modulated directly to microwave frequency, but only phase shift keying (PSK) modulation method is applicable.
