  Shruthi Raghavendra,  Sharmila K. P.

Recent advancement in vehicular wireless applications is also a major contributing factor in spectrum scarcity. Cognitive radio technique is applied to Vehicular Ad hoc Networks (VANETs) to increase frequency bandwidth. Fast and reliable detection of primary user is the key component of cognitive radio networks. In this paper, we are considering a CR system that uses spectrum sensing based on the Time-Domain Symbol Cross-correlation (TDSC) technique, This paper examines the performance of spectrum sensing using Time-Domain Symbol Cross-correlation over correlated Rayleigh channel, in the context of the Vehicular Ad-Hoc Networks for which the TDSC method is explained analytically and illustrated with numerical results obtained from simulations. The relevant simulation results are presented to support our analytical results for average miss detection probability.
