Performance Analysis of a Modified SC-FDMA-DSCDMA Technique for 4G Wireless Communication

Figure 6

PAPR performance of the proposed SC-FDMA-DSCDMA technique compared with other multicarrier techniques. QPSK modulation with FFT size being 256. PAPR performance of the proposed technique is best: 1 dB better than SC-FDMA and 2 dB better than Luo and Xiong [5].
