Simulation of OFDM based Software Defined Radio for FDD-LTE Uplink

This paper gives an overview of Simulation of Software defined radio for Long Term Evolution (LTE) uplink based on Orthogonal Frequency division Multiplexing. Long Term Evolution is the outcome of the development of 3rd generation partnership project (3GPP). This Evolution is a great boom in the mobile technologies towards 4th generation. As the Expected frequency range of LTE - 3GPP standard, it can accommodate an uplink speed of up to 50 Mbps and a downlink speed of up to 100 Mbps. In this paper, baseband section of Software defined radio is simulated for FDD based LTE uplink design using MATLAB. Uplink design is formulated using SC- FDMA multiple access scheme with proposed methodology. A clipped Selective mapping technique is used in conjunction with Root raised cosine pulse shaping to reduce the PAPR content of SCFDMA which is a main disadvantage of OFDM systems.
