Long Term Evolution uses Multi-Carrier Frequency Division Multiple Access (MCFDMA) instead of Orthogonal Frequency Division Multiple Access (OFDMA) for uplink communication as it has a lowPeak to Average Power Ratio (PAPR) compared to OFDMA. One of the major problems with multicarrier fluctuations is the high PAPR of the transmitted signal. To receive high PAPR, a power amplifier should be used in a specific location that reduces the efficiency of the power amplifier. In this paper, a new PAPR reduction process for MC FDMA signals is proposed based on Discrete Hartley Transform (DHT) and in companding. It is based on smooth air performance to limit PAPR to MC-FDMA uplink systems and the proposed transform does not increase the signal strength and achieves a better Bit Error Rate (BER). A new error function (NERF) is used that provides better performance when the QPSK process is implemented. The simulation effects of MC FDMA compression with companding and without companding are comparable and the proposed procedure achieves a significant reduction in PAPR signal for MC FDMA.
