The dedicated short-range communication (DSRC) system is the evolving technique used in the field of intelligent transport system (ITS) and Electronic Toll Collection (ETC).The DSRC standards employs FM0 and Manchester encoding techniques to obtain dc-balance and enhances signal reliability.The codeword structure of FM0 and Manchester are different, thus limiting the hardware potential of existing DSRC systems.In this paper similarity oriented logic simplification (SOLS) technique is proposed to fully re-utilise the existing hardware and behavioural model is simulated using XILINX 14.1 software and outputs are verified using XILINX VIRTEX-5 kit.This encoding technique fully supports DSRC standards of America, Europe and Japan.This paper proposes the technique to improve reliable performance over existing DSRC systems.
