Abstract :
We introduce vehicle multi-hop communication (VMC) project in Korea, which provides vehicle to vehicle and vehicle to Infra communications. At first, technical issues such as high mobility, low packet latency and high density are discussed. And we propose Mid-amble based channel estimation and hybrid MAC for vehicle safety and traffic information applications. Mid-amble based channel estimation is effective for long packet transmission and hybrid MAC has better performance for high density user environments. To show the merits of the proposed technologies, radio link performance is analyzed in high mobility radio channel by computer simulation.
