VIRTUAL MIMO FOR VEHICULAR COMMUNICATION SYSTEMS

Abstract

This paper provides a simulation study for the quality of vehicle communication system by using a Virtual Multiple-Input Multiple-Output (VMIMO) used in Ultrawide Band (UWB) wireless communication, merged with orthogonal pulse shaping using modified Hermite polynomial. The simulation compares between Zero-Forcing (ZF) and Minimum Square Error (MMSE) Detection Techniques performance through bit-error-rate analysis. The simulation includes different scenarios for vehicular communication: The Vehicle to Vehicle (V2V) and the Vehicle to Infrastructure (V2I). Firstly, the Non-Line-of-Sight (NLOS), secondly the Line-of-Sight (LOS) scenarios. Moreover, the simulation considers the effect of path-loss and noise on transmitted signal, besides the comparison with QAM (Quadratic amplitude modulation), QPSK (quadratic pulse shift keying) and (Binary pulse shift keying) BPSK modulations. The simulation result is useful for the design of vehicle communication system including several cases of vehicles communication such as the V2V and V2I. The final results recommend BPSK-MMSE communication for both the LOS and NLOS scenarios for the V2V and V2I.
