Performance Evaluation of 28 and 73 GHz Ultra High Frequency Bands for Outdoor MIMO
AbstractIn this paper, the performance of two ultra-high frequency for outdoor performance of Multiple Input Multiple Output (MIMO) systems is analyzed. A simulation with realistic scenarios is set up using the Statistical Spatial Channel Model (SSCM) over frequency selective Rayleigh fading channel. The channel behavior of MIMO for two Ultra high frequencies (28 and 73 GHz) using different number of transmitter and receiver antenna, different receiver distance and different propagation scenario is investigated. Parameters are calculated and compared to investigate the MIMO performance for these frequencies such as path loss and received power. The effect of using different antenna is also investigated. The results are analyzed, and a conclusion was drawn about the main characteristics and the usability of these ultra-high frequencies. The investigated frequencies are candidate to become a key component for cellular 5G networks and thus it is vital to investigate them to assist engineers in designing their 5G network.
