Comparative Analysis Of Propagation Path Loss Models In Lte Networks

The paper analyzes the radio propagation model that can be employed in case of 4th Generation (4G) cellular networks which is referred as long term evolution abbreviated as LTE. Since correctness of any propagation model depends on topography clutter and other constraints. An understanding of the large scale transmission effects is very imperative for blueprint of appropriate communication system. In this, various propagation models are studied and compared against measured data available in [1] for the dense urban region of Delhi NCR, India at 1800 MHz. In the investigation part; path loss values are observed over a distance of 2 Km at every 100 meter for all the models used. Analytical result shows that free space model has the minimum path loss in case of values of frequency values, antenna heights that are specified. Ericsson, Cost-231 along with ECC models have shown preferable outcomes in comparison toh the experimental data attained in the vicinity of NCR, Delhi (INDIA). Amongst all the models under analysis, Ericsson has shown the best result. These results have been obtained both on Matlab and Simulink. Both are coming equivalent. The best model as per the result is optimized to make it closer to the measured data.
