摘要：In this paper, design and implementation of 4G SC-FDMA transceiver on FPGA is done and explained. Long Term Evolution (LTE) is next generation mobile communication standard from 3GPP, it is based on OFDMA) in Downlink Transmission and SC-FDMA in uplink Transmission. SC-FDMA is based on Frequency Division Multiple Access scheme. When compared with other multiple access scheme, it deals with the multiple users in a shared communication systems. SC-FDMA is also called as linearly pre-coded OFDMA, in the sense it has the additional discrete time Fourier transform (DFT) processing in SC-FDMA. The main advantage of SC-FDMA over OFDMA is low Peak to average power ratio, so the power transmission is low when compared. This work proposes a run time reconfiguration architecture for the SC-FDMA. Where the bandwidth and sub carrier mapping schemes of SC-FDMA can be changed. Real time FPGA implementation results are captured in the Chipscope Pro Embedded Logic analyzer.
