The study of SC-FDE in HF communication
This paper presents SC-FDE implementation in HF communication.We introduce the basic theory of SC-FDE,and analyze the problems of PAR,frequency shift,computation complexity about SC-FDE.At last,we simulate the performance of SC-FDE in HF channel.The study shows that SC-FDE is a HF waveform design method equivalent to OFDM and has good future.
The similarity and difference of regional distributions between management science publication and NSFC's management science fund are compared. Two scientometric models rank-frequency distribution and concentration measurement are used to show whether or not the amount of grants awarded to different provinces by the National Natural Science Foundation of China (NSFC) match with the research capacity of given provinces as indicated by its management science publication
