Dedicated Short Range Communication Techniques

DSRC if implemented efficiently in India reduces the risks of vehicle accidents due to mismanagement of traffic and delays due to traffic congestion by a large amount. The DSRC protocols generally adopt FM0 and; Manchester; codes to enhance the signal reliability and achieve dc-balance. The disadvantages of using the conventional FM0 and Manchester techniques individually is that area utilization is less as compared to the similarity-oriented logic simplification (SOLS) technique. SOLS technique combines the FM0 and Manchester encoding techniques to overcome these disadvantages and implement DSRC. Another disadvantage that we face with FM0 and Manchester is that the output that we get is unbalanced dc logic in comparison to a balanced DC logic with SOLS that is easier to implement. In this project we have implemented all the basic elements of SOLS, FM0, and Manchester & SOLS circuitry using Verilog Xilinx in order to understand basic functionality of these blocks. Further, we have implemented the SOLS technique in Orcad PSpice using Resistor Transistor Logic (RTL), Domino Logic, Transmission Gate, Transistor Transistor Logic (TTL) and CMOS logic.
