Abstract

SC-FDMA (Single carrier-Frequency Division Multiple Access) with lower PAPR (Peak-to-Average Power Ratio) than OFDMA (Orthogonal Frequency Division Multiple Access) is an attractive alternative to OFDMA. SC-FDMA also possesses basic advantages of OFDM. The 3rd generation partnership project (3GPP) long term evolution (LTE) standard has adopted orthogonal frequency division multiplexing access (OFDMA) in downlink and single carrier frequency division multiple access (SCFDMA) scheme for the uplink transmissions. In this paper, we competitively analyze the PAPR of SC-FDMA signals with pulse selective mapping, partial transmit sequence and proposed pilot sequences. We analytically derive the time domain SC-FDMA signals and numerically compare PAPR characteristics using the complementary cumulative distribution function (CCDF) of PAPR.
