Abstract

OFDM is a broadband wireless technology which supports data rates in excess of 100 Mbps. In addition to this, OFDM has some limitations as it requires strict frequency synchronization and low peak to average power ratio. So considering DFT-OFDMA, which performance in terms of PAPR, is equivalent to SC-FDMA. This paper represents the suitability of using OFDMA in the up-link for high-data-rate scenarios in local area by considering target performance metrics PAPR. The proposed design shows PAPR performance varies depending on the subcarrier allocation method. It has been also shown that performance of the PAPR by DFT-spreading technique with IFDMA and LFDMA, varying with roll-off factor ? of the RC (Raised-Cosine) filter. Effect of the number of subcarriers on PAPR performance is also discussed in this paper.
