Abstract: The automotive industry is emerging aggressively towards the direction of advanced active safety. The automotive industry is aiming to work for the development of Dedicated Short Range Communication (DSRC) technology, for the purpose in vehicle-tovehicle and vehicle-to-roadside communication. To transmit the vehicular information and broadcast vehicle position, DSRC communication technology is adopt as bridge. This work is devoted to develop the encoding techniques for WAVE/DSRC applications. The DSRC standards generally make use of FM0 and Manchester encoding to achieve dc balance and enhancing signal reliability. Nevertheless, the diversity of coding between FM0 and Manchester codes limits the ability to design a fully utilize hardware architecture for both. The Reuse oriented logic simplification (ROLS) technique is proposed here so that the Hardware utilization rate (HUR) will reach to 100% from 57% for both encoding techniques. The proposed architecture will have less delay, area as compared to existing architecture. In this paper the architecture analyzed to reduce the number of components. Using both encodings the area, delay, and power is reduced in DSRC. The power consumption is 22132.181nW for both encoding, and area is 193µm2 . The encoding technique in this work supports the DSRC standards used by several organizations of America, Japan and Europe
