Physical Layer Performance Analysis of LTE Networks for Downlink

Abstract

The Long Term Evolution (LTE) and LTE-Advanced are two most versatile mobile technologies in the cellular networks that have been deployed at a fast pace all over the world. Theses technologies have been aggressively deployed than any other cellular technology previously and their adoption rate by the cellular operators over the world has surpassed even Global System for Mobile (GSM) and the Universal Mobile Telecommunications System (UMTS) that were deployed in the 1990s & early 2000s respectively. In this paper, we investigate several key LTE physical layer parameters such as Bit Error Rate (BER), Block Error Rate (BLER), throughput, Cumulative Distribution Function (CDF), macroscopic path losses, Signal to Noise Ratio (SNR) etc. We comprehensively evaluate & analyze the performance of above mentioned parameters using various dependent parameters & provide the simulation results for each parameter considered. At the end we conclude & discuss the performance simulation results.
