  • Performance Evaluation of SC-FDMA Systems Using Wireless Images

    Performance Evaluation of SC-FDMA Systems Using Wireless Images K. M. Al-soufy, F. S. Al-kamali and F. A. Al-fuhaidy Department of Electrical, Faculty of Engineering and Architecture, Ibb University, Ibb, Yemen Recently, single crarrier frequency division multiple access (SC-FDMA) has drawn great attention in wireless communications due to its low peak-to-average power ratio and low sensitivity to carrier frequency offsets. The aim of this paper is to investigate and test the wireless image transmission over SC-FDMA with consideration of different basis…
