Empirical Arrival Angular Profile Prediction Formula for Mobile Communication Systems

Arrival angular profile model is necessary to evaluate accurately the spatial processing techniques such as adaptive array antenna (AAA) and multi-input-multi-output (MIMO). Existing models do not always predict the actual values accurately in various environments. In this paper, we propose a novel empirical arrival angular profile prediction formula that can consider the distance from BS, antenna height of the base station, and city structure (building height) generated from the data measured in various field environments. As the proposed formula is a relatively simple equation and can predict the spatial correlation accurately, it is convenient and useful for evaluating the characteristics of radio transmission systems such as MIMO and AAA, etc. in various areas.
