| Abstract: | This paper studies the technology of Multi-carrier Modulation via DSP.The purpose of studying is searching for a method which can improve data transmission in VHF communication.First,this paper analyzes the state of data transmission in VHF communication.The traditional data transmission uses on single carrier,and the result is low data rate and low reliability due to some disadvantages such as the limited band width.Now Multi-carrier Modulation becomes possible because of the devolepment of DSP.Multi-carri... |
