Scheduling algorithms for channel-sensitive utilizing SC-FDMA in uplink

In this paper, a new approach is considered, which are different categories to reduce the bits error rate and PAPR reduction, utilizing single carrier frequency division multiple access SC-FDMA and orthogonal frequency division multiple access OFDMA. This paper discusses the appropriateness of using OFDMA or SC-FDMA in the uplink for high-data-rate, considering a target performance metrics the PAPR. Particularly, the PAPR analysis shows that a localized (not distributed) allocation of the resource blocks (RBs) in the frequency domain shall be employed for SC-FDMA in order to keep its advantages over OFDMA in terms of PAPR reduction. In addition, from the multiuser variety gain evaluation emerges the fact that the impact of different RB sizes and bandwidth configurations is low.
