摘要：
One of the main drawbacks of OFDM systems is the high Peak-to-Average Power ratio, which could limit transmission efficiency and efficient use of HPA. In this paper we present a modified tone reservation scheme for PAPR reduction using FFT iterations to generate the tones. In this Scheme, the reserve tones are designed to both cancel peaks and slightly increase the average power to induce a better PAPR reduction.. The tones are generated by means of 2 FFT operations and the process is sometimes iterated to achieve better PAPR reductions. This scheme achieves a significant PAPR reduction of at least 4.6dB when about 4% of the carriers are used as reserve tones and with even lesser iterations when simulated in an OFDM system.
