Reconfigurable Channel Interference Reduction for Vehicular Communication Applications

Abstract

Vehicular Communication systems, an application of wireless communication is an increasing area of communication between the vehicles and other roadside infrastructure in which allocation of wireless channels are used to share information among vehicles and infrastructure and hence these channels are used for the development and implementation of vehicular communication systems. The 10 MHz wide channels in 5.9GHz spectrum band are reserved for this purpose by two main protocols the WAVE standards proposed by IEEE in the United States and ETSI ITS-G5 in Europe. But still the cross ?channel interference affect the vehicular communication systems. So to reduce these problems, this paper presents the implementation of two-stage low pass equiripple FIR filter, target to be integrated with digital baseband receiver chain of vehicular communication platform. The proposed filter has been developed using Matlab and Xilinx DSP Tools and implemented with XST software using Spartan 3E and Virtex 2p FPGA device to ensure the minimum delay generated in operation and to show the effectiveness of the proposed filter. The results show that the processing speed is efficiently optimized up to 19.70 % for stage 1 and 10.50 % for stage 2 using virtex 2p over Spartan 3E with maximum area utilization.
