Popis | Millimeter wave (mmWave) communication has raised increasing attentions from both academia and industry due to its exceptional advantages. As a part 5G New Radio mobile systems, mmWave communications adopt much higher carrier frequencies and thus come with advantages including huge bandwidth, narrow beam, and high transmission quality. No doubt, there are disadvantages e.g., severe signal attenuation, easily blocked by obstacles, and small coverage, due to its short wavelengths. Hence, the major challenge is to overcome its shortcomings while fully utilizing its advantages. In this paper, we present the new enhanced model which is based on a ray tracing algorithm rather than goniometric functions. The main advantage of presented model over the old one is 3D path-loss calculation, reduced algorithm together with computational complexity. The results from two simulation scenarios are discussed to provide better understanding of the importance of the thickness of blockage objects. To further increase the understandability, we present the scenarios blockage. |
