PAPR Reduction of Waveforms for 5G-6G Communications
Anu Bharti
Abstract: Orthogonal Frequency Division Multiplexing (OFDM) is a remarkably efficient multicarrier modulation technique. It offers high data rates, high spectral efficiency, reduced complexity, and is resistant to frequency selective fading. Flexible for inter-symbol and inter-frame interference. With all these benefits, OFDM is used in 4G and also meets the requirements of 5G NR. CPOFDM / OFDMA is used for 5G downlink. OFDM is a multi-carrier technique, and one of the main demerit of this technique is high peak-to-average power ratio (PAPR). When PAPR is limited, the power amplifier operates more efficiently and extends the battery life of the device. In this study, we performed various PAPR reduction techniques such as Amplitude Clipping, Selective mapping, and Partial transmit sequences, and compared the simulation results in MATLAB.
