Performance Analysis of LS Channel Estimation Technique for IEEE 802.11p WAVE System
IEEE 802.11p  based WAVE, which is a well-known wireless vehicular communication technology, is gaining
worldwide attention as a medium/short range wireless communication system supporting public safety and personal
communication between vehicles (V2V) and between vehicles and infrastructure (V2I) , . However, accurate channel
estimation is difficult under outdoor environments in the case of IEEE 802.11p based WAVE because data are transmitted in
running vehicles. To overcome this difficulty, diverse studies on channel estimation are being carried out currently -.
This study compared the symbol error rate (SER) performance between the perfect channel estimation method in an IEEE
802.11p based WAVE system and the LS channel estimation method using pilot signals.
