SC-FDMA link has been modeled and proposed to design this link using LabVIEW and the simulation results show that the PAPR and BER parameters of the proposed SC- FDMA link design are significantly lower than the OFDMA in downlink.Abstract:
Single-Carrier Frequency Division Multiple-Access (SC-FDMA) is used in uplink data transmission in Long-Term Evaluation (LTE) due to its low Peak-to-Average Power Ratio (PAPR) properties. In this paper, SC-FDMA link has been modeled and proposed to design this link using LabVIEW. The real-time data transmission through the SC-FDMA link is carried out using Software Defined Radio (SDR) testbed which is implemented using Universal Software Radio Peripheral (USRP) devices. The data transmission and reception are carried out through SC-FDMA link and the performance evaluation is estimated for PAPR and Bit Error Rate (BER). The simulation results show that the PAPR and BER parameters of the proposed SC-FDMA link design are significantly lower than the OFDMA in downlink. Moreover, the simulation of BER with different modulation schemes is carried out for different Signal to Noise Ratio (SNR) values. The analysis of PAPR impacts the OFDMA waveform and benefits on SC-FDMA transmission link in any channel condition.read more
