20 15 southeast university communication postgraduate entrance examination for help, is the information on the radio forum reliable, is it necessary for foreign schools to buy it?
I still have to attend the professional class of Southeast University Radio Postgraduate Forum. There are professional courses and year-round questions and answers, and you can enjoy the answers in previous years. This is also very helpful. At present, the professional difficulty and requirements of the School of Information in the Fourth Hospital are very high, and there are not many colleges and universities with signal and digital examination modes in China, and there are not many resources for reference.
