| Abstract: | In a great variety of fields of modern communication,frequency-division multiplexing is a commonly used means to improve the efficiency of the communication system,and this method is widely used in carrier system telephone,broadcasting,television,satellite communications,and so on.In this paper,some typical modulation methods have been compared through analyzing of the movements of spectrum in the linear modulation,and modulation methods for different signal in frequency-division multiplexing have been discussed. |
