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 functions, different modulation schemes and different subcarriers mapping schemes. Several experiments are carried out and the obtained results show that the wireless images transmission over SC-FDMA systems is possible efficiently. Simulation results also show that the interleaved systems significantly improve the clarity of the received image and their performances are better than that of the localized systems irrespective of the wireless channel or the modulation scheme used. Moreover, the results show that the discrete cosine transform (DCT)-based SC-FDMA (DCT-SC-FDMA) and discrete sine transform (DST)-based SC-FDMA (DST-SC-FDMA) system achieve better performance than the conventional discrete Fourier transform (DFT)-based SC-FDMA (DFT-SC-FDMA) system in terms of Mean Square Error (MSE) and Peak Signal-to-Noise Ratio (PSNR) values.
