Math must be good! The mathematics of communication is the first (including advanced mathematics, probability theory and linear algebra) and the most difficult. Simply analyze it and you will know, because communication engineering mainly studies wireless communication, and the carrier of wireless communication is electromagnetic wave. The transmission of electromagnetic signal needs to calculate power and spectrum, and mainly uses the knowledge of integral (the first half of high number is simple calculus, which is basically the same as that of grade three, and it is very simple to learn, but it becomes more difficult after multiple integrals in the second semester of high number, so pay attention to study hard. ), in addition, the propagation of electromagnetic waves is random, and the analysis requires the knowledge of probability theory. In the specialized course "Communication Principle", it is mainly to calculate the loss and noise interference of wireless signal energy transmission, which is mainly related to the average power. Most of the formulas are integral formulas, plus some knowledge of probability theory. In signal and system, digital signal processing and other professional courses, the main applied mathematical knowledge is Fourier transform, convolution and correlation. In short, mathematics is very, very important for communication!

In addition, it is more theoretical because wireless signals are abstract. Most of the analysis is the theoretical analysis of mathematical calculation power and spectrum.

But it has something to do with what you want to do in the future. If you are not doing pure communication research, there is no need to apply such a deep theory. The final work of communication major is basically related to software, and most of them are engaged in software development of communication equipment. So many students majoring in communication at Beihou University went to Internet companies.
