2, the difference between communication and information system and signal and signal processing:
The former focuses on communication interaction, such as how to code 0 and 1 (channel coding), MIMO and so on, as well as communication network architecture, channel model and so on, focusing on interaction and communication, regardless of the content of this signal, only responsible for the accurate transmission of 0~ 1, so it often involves modulation, decoding, interleaving, error correction and so on. The general direction is the extension of the propagation principle.
The latter focuses on signal processing. In this direction, what we care about is not how to interact and get the signal, but what to do after getting this signal, such as image signal enhancement, noise filtering, recognition, compression, coding and decoding and so on. And the sound signal is also corresponding, which is more closely combined with medicine. For example, medical image signals and X-ray images often need to be processed. Different processing methods are adopted according to different signals. There are also some studies on transformation. It has a wide range of applications, depending on what this signal is. The general direction is the extension of discrete-time signal processing.
So, for example, the current telephone network, the former focuses on the interaction in the middle (operators, mobile, telecommunications, China Unicom), while the latter focuses on the processing at both ends (source coding, filtering and equalization in the terminal factory).
What is the postgraduate entrance examination for communication major?
First of all, the postgraduate entrance examination for communication major consists of four courses: 10 1 politics, 20 1 English, 30 1 math I (communication is math I). These three courses are national unified examinations, and the topics are the same all over the country, but the specialized courses are different in different schools.
How to find out what to test in specialized courses in colleges and universities?
Log on to the website of your graduate school or Baidu to inquire about the examination subjects and bibliography of your major. If there is no bibliography, you can check it in the graduate forum of the school or ask your brothers and sisters directly. (Baidu search keywords: XXX University Graduate School or 20 14 XXX University Graduate Admissions Directory).
