Abstract
In Message-Driven Frequency Hopping(MDFH) system,part of the message stream will act as the Pseudo Noise(PN) sequence,and will be transmitted through hopping frequency control.The MDFH system is described firstly;and then a synchronization method for the receiver,which includes design of pre-sequence and Cyclic Prefix(CP),is put forward;the BER performance of the system in multipath channel and AWGN channel is simulated at last.Through frame detecting,symbol timing,frequency synchronization,the results show that the BER performance of the system has been greatly improved compared with that of the original MDFH system.关键词
