This subject is a rapidly developing and dynamic field of information science and technology, especially digital mobile communication, optical fiber communication and internet network communication, which makes people reach unprecedented convenience in transmitting and obtaining information. Communication engineering has a very broad development prospect, and it is also one of the professions with a serious shortage of talents. This major studies the knowledge of communication technology, communication system and communication network, and can engage in the research, design, manufacture and operation of communication field, and engage in the development and application of communication technology and equipment in various departments of national economy and national defense industry. After graduation, I can engage in research, design, technology introduction and technology development in the fields of wireless communication, television, large-scale integrated circuits, intelligent instruments and applied electronics, design and communication engineering. Communication engineering studies the transmission of information from a sender (source) to one or more receivers (destination) by electric pulses in the form of electromagnetic waves, sound waves or light waves. Whether the receiver can correctly identify the information depends on the loss in transmission. Signal processing is an important link in communication engineering, including filtering, coding and decoding.
