There are basically no good schools in Liaoning province, and the big workers are relatively good. The rest of Dalian Maritime and Northeastern University are not very good.
The college entrance examination is more difficult and restrictive. It is suggested to change to an undergraduate course and take the exam again.
The following is the answer before copying:
There are three directions to choose from: signal and information processing, communication and information system, electromagnetic field and microwave.
It depends on the examination subjects designated by the school.
The preliminary examination of signal and information processing, communication and information system will generally take one or two courses in communication principle, signal and system and digital signal processing, and there may be digital, analog and microcomputer principle interfaces.
Electromagnetic field and microwave, electromagnetic field and electromagnetic wave must be tested. Other courses above may be tested, depending on the school, but this direction is a bit cold. The most counterpart is signal and information processing.
In addition, some schools also have majors in circuits and systems in communication.
Beihou, Xidian, Tsinghua, Tianda, Dongda, Jiaotong University, Zhejiang University and Chengdian are all quite good, as are Wuda University, Huake University, Beijing Jiaotong University and South China University of Technology.
