Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a device and method for realizing a digital broadband excitation source. Background technique [0002] With the development of modern communication technology and the upgrading of communication systems, the capacity of communication systems is getting larger and the rate of information transmission is getting higher and higher. Especially in complex communication environments, due to the existence of various interferences, communication systems are required to have a lot of Strong anti-interference, anti-detection, confidentiality and other functions. As one of the important components of the wireless communication system, the emission excitation source plays an important role in wireless communication. To enhance the ability of the communication system to cope with complex environments, it is first necessary to correspondingly enhance the ability of the emission e...
