Orthogonal Frequency Division Multiplexing (OFDM) system is used for the reducing almost every kind of interference in any communication system. For designing OFDM system need to use FFT and IDFT phenomena of signal processing, in this work mainly concern to improve peak to average power ratio for this system because this system is multicarrier system,

One of the major drawbacks of OFDM is its high peak-to-average power ratio (PAPR) which can result in poor power efficiency and serious distortion in the transmitter amplifier. Tone reservation (TR) is a technique designed to combat this problem by reserving a number of sub-carriers (tones) in the frequency domain to generate a cancellation signal in ...

Peak to Average Power Ratio (PAPR) Minimizing Techniques for Helical Interleaved OFDM System
2017Orthogonal frequency-division multiplexing (OFDM) is a multi-carrier, multi rate, multi symbol, frequency division multiplexing transmission system. In which a single high data rate stream is divided in to a number of low data rate streams. High spectral efficiency due to orthogonal subcarriers is the major advantage of this system.
