Abstract :
Future DSRC applications need flexible and robust air interface technology to support high and low data rate services in harsh mobile environments. First we analyze various DSRC applications for their data requirement and present typical DSRC channel scenarios with their parameters. To address this variety of scenarios, we propose a hybrid OFDM architecture that is a combination of single carrier and multicarrier (OFDM) communication systems for DSRC services. Single carrier devices communicate in an OFDMA scheme in the uplink for more spectral efficiency reasons. Simulation results shows that it is feasible to operate hybrid OFDM for a variety of DSRC applications
