Abstract :
Novel techniques of Road Side Unit (RSU) selection for handover were investigated in this study. It was determined that there are currently no efficient RSU selection schemes, which is a severe issue for conventional techniques following the current IEEE 802.11p standard. Recently, data-aided OFDM (DA-OFDM), such as Pseudo-Random-Postfix-OFDM (PRP-OFDM) and Time Domain Synchronous-OFDM (TDS-OFDM), have received attention because of their capability for higher effectiveness with better transmission quality. This study derived the maximum likelihood (ML) channel estimation for DA-OFDM and evaluated and compared proposed techniques by computer simulations.
