Performance Evaluation of Adaptive Modulation System with STTD in Vehicle-to-Vehicle Communication Environment

In this paper, We analyzed performance of adaptive modulation system with STTD in vehicle-to-vehicle communication environment. Transmission error of system is increased by ISI according to delay wave in wireless channel environment. Therefore, We analyzed performance that it is applied adaptive modulation system with STTD to reduce ISI's effect. As a results, Data transmission of high speed-high quality could know possible by applying adaptive modulation system with STTD. Because of selected high modulation mode in low SNR.
