Impact of Alamouti Space – Time Block Coding on the Performance of Vehicle – to – Vehicle Communication

Abstract

A network that has recently received a lot of interest is the Vehicular Ad hoc Network VANET. Vehicle – to – Vehicle V2V communication is the conventional method in VANET communication, where vehicles can share information regarding the road status such as a warning message related to the incidence of an accident. The aim of this paper is the use of Multiple – Input – Multiple – Output MIMO diversity technique called Alamouti Space-Time Block Coding STBC as a channel coding in V2V communication. The simulation tests were constructed according to the conditions of vehicles speeds, modulations and the distances between the vehicles. These tests included both symmetric and asymmetric channels. The results showed that Alamouti STBC is suitable for slow fading channel communication rather than for mobility communication such as V2V.
