Performance investigation of LTE systems based on NI PXIe-5644R vector signal transceiver

LTE is acronym for “Long Term Evolution” used as a new technology that suggests intensifications to prevailing mobile technologies. LTE is 4G (4th Generation) technology that focuses to afford excelling features of service as compare to other technology. LTE is extensively called the competent and adversary technology to WiMAX because of its wireless nature and mobile services. LTE is one of the most interesting fields of research due to its higher data rate, low latency, high spectral efficiency and improved Quality of Service (QoS) even for the cell edge users. In this paper, the main objective is to investigate a downlink and uplink physical layer performance of Long Term Evolution system based on LTE Release 10. The performance of LTE system is analyzed using Real time simulation with the help of sophisticated and accurate hardware from national instruments based PXIe-1062 vector signal transceiver 5644. The performance of LTE is analyzed at 3MHz, 5MHz, 10MHz, 15MHz. In this study, the performance LTE of downlink and uplink transmission is investigated depending on different scenarios for the physical layer.
