Compensating the effect of Doppler shift in a vehicular network

摘要: Wireless channels operate through the transmission of electromagnetic signals from transmitter to receiver. In a fixed wireless network, medium is often distorted or disrupted by inherent natural phenomenon which in turn corrupt, obstruct cause most data transmitted over channel generally get garbled. vehicular greater complexity added as result fast mobility nodes within network. It therefore becomes very difficult for receiver decode efficiently. Based on IEEE standard, communication between two mobile can only be possible if minimum required threshold has been met. this paper, Direct Development Method (DDM) strategy presented that seeks combat effect Doppler Shift (DS) The proposed approach developed based principle basic theory and validated simulations. demonstrated it achieve good link mobiles moving at relative speed up 250 km/h taking into account prescribed threshold.
