Performance evaluation for multi-antenna vehicular communication based on IEEE 802.11p standard

Abstract

Multi-input multi-output (MEMO) has been a promising technique for wireless communication areas, such as intelligent transportation systems. In this paper, we present performance evaluation of a multi-antenna transceiver for Wireless Access in Vehicular Environments (WAVE) according to IEEE 802.11p standard. Herein, MIMO WAVE is performed by employing three MIMO schemes, namely, Alamouti, vertical BLAST (V-BLAST) and space shift keying (SSK) scheme. The above three MIMO schemes are discussed and compared, considering the influence of different driving velocity and with/without line of sight (LOS) on the system performance. Based on the analysis and simulation results, it can be found that compared with single antenna systems, V-BLAST scheme would significantly increase the transmission data rate, while Alamouti and SSK scheme could improve the reliability and robustness even under poor receive conditions.
