Communication among vehicles is offering a lot of benefits and has testified improvement on safety, efficiency and possible automation of the traffic. A lot of research has been focused on measurement campaigns, by investigating different situation for communication between cars in traffic. Lately, a hot topic is the simulation of the communication among cars and the environment. Therefore the focus of this thesis has been on advancing these simulation for IEEE 802.11p and Long Term Evolution (LTE) by performing updates with new modules and performance metrics. One contribution of this thesis is exploring the simulation framework for DSRC and LTE known as VeinsLTE and performing updates to capture various environmental effects. These modules capture the attenuation effects on signal power caused by buildings, vehicles and other factors. Adopting the framework with these modules has offered a wider range for simulation and comparisons. Another aspect that this thesis has been focused on is V2V channel models, which are based on realistic measurements and make it possible to overcome some limitations of the simulation in different regions. Computation of performance metrics such as delay and throughput has been achieved. These performance metrics offer another scope for analysis and comparisons among the technologies LTE and DSRC. Simulations will be focused on investigating different scenarios by covering various geographical regions such as intersections, roundabouts and highways. Comparison of the analysis results with realistic measurements results will given to the simulation results a strong validation. I Acknowledgement First, I would like to express my gratitude to my supervisors Emma Fitzgerald at LTH and Mikael Nilsson at Volvo Cars for their support and guidance in this thesis project. I would like to thank as well my assistant supervisor Taimoor Abbas at Volvo Cars for his help and support during this project. I am very grateful in working with all of you during this interesting journey with many challenges and inspirations. I am very grateful to all my professors in LTH, your guidance and knowledge during this master studies are highly appreciated from me. A special thanks to my manager Magnus Eek and the wireless team at Volvo Cars for initiating the thesis project. The biggest appreciation to my family for their love and support, my mother Aferdita, my father Halit, my brothers Festim and Milot and my love Azra.

Traditional test setups for multiple-input multiple-output (MIMO) communication systems have been developed for relatively small devices such as handsets and tablets. At the same time, there is a desire to replace vehicular field tests with lab testing, for more efficient and accurate testing. This paper evaluates over-the-air verification methods for MIMO communication systems, which may incorporate vehicle-sized antenna systems and that can be implemented in a lab. Different methods are compared by means of a round robin campaign. The results from the campaign indicate that performance assessment representative to real-world operation can be achieved.
