Partial transmit sequence (PTS) and selective mapping (SLM), are two algorithms used for peak-to-average power ratio (PAPR) reduction in multicarrier transmissions. In this paper, these techniques are applied for single carrier transmission system enhancement. The advantage of these algorithms, that they have no effect on the bit error (BER) of the system. But it will increase the complexity of the system due to the need for additional inverse discrete fourier transform IDFT calculations, search complexity for optimum phase factor. These algorithms are implemented on a single carrier frequency division multiple access (SCFDMA) system. SC-FDMA is used in Long Term Evaluation (LTE) of 3rd Generation Partnership Project (3GPP) as a strong candidate for uplink multiple access scheme. Simulations show that the proposed system with these two algorithms introduces a significant PAPR reduction compared to conventional system. There is a tradeoff between the PAPR reduction and the transmitter complexity. Due to the need for additional IDFT blocks, the complexity increased and due to side information, data rate has small decrease. Different simulation parameters are used for these algorithms which provide a good indication for selection of optimum technique with optimum parameters.
