Impact of the Solid State Power Amplifier on the BER Performance of the SC-FDMA System

Abstract: This paper presents an investigation of the impact of the solid state power amplifier SSPA on the performance of localized SC-FDMA and interleaved SC-FDMA system. SSPA is used for amplification of the SC-FDMA signal. The input back off IBO is simulated for pederstain A (Ped A) and vehicular A (Veh A) channel with MMSE equalizer. SSPA is used with IBO=1,3,6 dB and P=2 values. Simulation results show that the IBO of the SSPA has a significant effect on the bit error performance BER of the SC-FDMA system. Finally, the SSPA should be designed carefully for the SC-FDMA system in order to provide a good performance.
