Requirements and test methods for vehicular antenna systems supporting cooperative ITS applications
Paper in proceedings, 2015
Antenna systems are crucial for the link performance of§ any wireless systems, including those supporting cooperative intelligent transport system (C-ITS) applications. It is therefore of great importance to define performance metrics that are relevant for C-ITS applications and a framework for measuring the metrics. In this paper, we propose to measure performance by cumulative distribution functions based on the output SNR of the antenna system under test. The SNR samples are collected with respect to the time scales relevant for C-ITS applications. The framework is suitable for both computer simulations and over-the-air measurements and can handle antenna systems that are time-varying and have multiple output ports.
