Popis:	The most upcoming technology for uplink transmission is Single-carrier FDMA (SC-FDMA) for LTE standard than OFDMA. The most preferable benefit of SC-FDMA is its slight Peak to Average Power Ratio (PAPR) for multiuser communication without affecting BER. The subcarrier mapping techniques are utilized for transmissions that are Distributed SC-FDMA and Localized SC-FDMA. The distributed mode of FDMA which is equidistant over entire bandwidth is Interleaved FDMA. In this paper, the PAPR and BER for both IFDMA and LFDMA also carried out for SC-FDMA versus OFDMA simulated and analyzed for different shift keying techniques.
