Abstract：The technique of the Linear Frequency Modulation(LFM) is proposed to solve the problems of the inter-symbol interference in this paper. For comparing with other modulation techniques, the BER is analyzed, and the simulation results are given. The theoretical prediction and the simulation results indicate that the LFM is very useful to depress the inter-symbol interference. The high transmitting speed is held in some areas where the average of the multi-path time dispersion is larger. The merits of the LFM are that it is not necessary to have an equalizer or the spread spectrum code modulation.
