Performance Analysis of LTE Physical Layer Based on Release 10

Abstract

Despite their tremendous success over the years, the wireless technologies are still confronted with some of the critical challenges such as, fading, multipath, and interference and spectrum limitations. To fulfill this, wireless communication industry worked hard and defined a new air interface for mobile communications. That is Long Term Evolution (LTE ),is the evolution of the Universal Mobile Telecommunication System describes standardization work by the 3rd Generation Partnership Project .It enhances the overall system performance by increasing the capacity of the system along with improving spectral efficiencies while reducing latencies. In order to achieve above requirements important changes have been required at the physical layer e.g. new modulation and coding schemes, reduced Transmission Time Interval (TTI) or advanced medium access techniques. In this paper, the main objective is to investigate a downlink and uplink physical layer performance of Long Term Evolution system.
