Performance Analysis of LTE Physical Layer Based on 3GPP- Release-8

Long Term Evolution is the last step towards the 4th generation of cellular networks. This revolution is necessitated by the unceasing increase in demand for high speed connection on LTE networks. This paper mainly focuses on performance evaluation of LTE physical layer to study and analysis the effect of transmitting and receiving data over noisy channels and how to resist loss in data by this simulation model for the downlink and uplink direction using matlab simulink based on 3GPP release 8 specifications to build up a simulation model for transmission voice over LTE networks, using the proposed simulation model in this paper to analysis the problems appeared in wireless air interface. Where, LTE is the latest high speed mobile broadband technology that is gaining widespread attention due to its high data rates and improved Quality of Service.
