Analyzing Doppler Effects in Millimeter Wave VANET Communications Using BCH Coding

The signal is attenuated and distorted in millimeter wave communication due to the short wavelength. Path loss is also significant because of its high carrier frequency. Further, it is more susceptible to rain and atmospheric attenuation. So the demand for reliable communication links and high transmission rates have tremendously increased during the last few years. The wireless communication in Vehicular Ad-Hoc Network (VANET) involves the transmission with lowest number of errors. The high mobility of the nodes in VANET results in an Induced Doppler Shift (IDS) in the carrier frequency at the receiver end. Therefore, effective communication in millimeter wave links for vehicular environments can be achieved by a deep understanding of the VANET communication channel, which is importantly different from those studied at frequencies below 6 GHz. Doppler shifts can negatively impact the reliability of V2V communication. In this paper, the analytical expression of the Doppler Effect for VANET communication is derived using our previous derived expression for Bose-Chaudhuri-Hocquenghem (BCH) coding in millimeter waves. It is observed that the proposed model results outmatch existing techniques addressing Doppler shifts.
