A Comprehensive Analysis of Lte Physical Layer
نویسنده
چکیده
The 3 rd Generation Partnership Project (3GPP) introduced Long Term Evolution (LTE) as the 3 rd generation of mobile communication standards. LTE Release 8 describes a mobile communication standard which supports up to 300 Mbps of data transmission in downlink using the OFDM scheme as well as up to 75 Mbps throughput for uplink using the SC-FDMA modulation. In this thesis, an in-depth study of LTE performance based on Release 8 is conducted for uplink and downlink under different scenarios. The main objective of this study is to investigate a comprehensive analysis of physical layer throughput of LTE Release8 based on standard parameters for different channel bandwidths, duplex schemes, antenna diversity and other scenarios. Our study of the FDD operation mode shows that the maximum throughput for downlink data is 299.122 by using 4 antenna ports with the least possible control overhead (one OFDM symbol assigned to PDCCH), 64-QAM data modulation scheme, the maximum code rate (0.92), and the maximum channel bandwidth (20 MHz). This throughput result is based on PDSCH that is used for data transmission only and does not include control information Synchronization Signals (P-SS and S-SS). Our study also shows that the maximum uplink throughput for the FDD operation is 71.97 Mbps excluding control channel information (PUCCH), and reference signals (demodulation reference signals and sounding reference signal). This maximum throughput result is based on assuming 64-QAM data modulation, maximum bandwidth (20 MHz), and 0.85 code rate. This study also presents other throughput results based on different parameters. Overall, this thesis provides a comprehensive investigation of the LTE performance analysis based on detailed physical layer parameters to fill the existing gap in current literature in performance study of LTE.
