PAPR comparison among traditional tone reservation and the proposed technique in Chirped-OFDM system As is shown in Fig. 3, we can see that the same C η only makes the tone reservation performance worse negligibly while it could reduce the calculation meaningfully through the structure of radix-2 FRFT algorithm.

In this letter, a novel scheme based on deep leaning, called tone reservation network (TRNet), is proposed for OFDM systems to improve the performance of the tone reservation (TR) technique. A. Tone Reservation PAPR Reduction Method Since for each transmit antenna link there are N r= jK pn K p i jnumber unused subcarriers within the active subcarrier band, then by sending dummy symbols (i.e., symbols not conveying information) in these subcarriers, the PAPR of the OFDM symbol can be reduced. We denote a set of unused Tone Reservation is one of them in which a small set of subcarriers are reserved for Peak Cancellation signal. This PCS helps to lower the PAPR of the whole signal. PAPR reduction by tone reservation depends heavily on the quantity, locations and the values of the PCS. Several people around the globe proposed distinct ways to implement this TR PAPR comparison among traditional tone reservation and the proposed technique in Chirped-OFDM system As is shown in Fig. 3, we can see that the same C η only makes the tone reservation performance worse negligibly while it could reduce the calculation meaningfully through the structure of radix-2 FRFT algorithm. Tone Reservation method for PAPR Reduction scheme Sung-Eun Park, Sung-Ryul Yun, Jae Yeol Kim, Dong Seek Park and Pan Yuh Joo Samsung Electronics Introduction In this paper, we consider the reduction of the potential large peak-to-average power ratio (PAPR) of an orthogonal frequency division multiplexing (OFDM) signal in communication systems.

In tone reservation (TR) based OFDM systems, the peak to average power ratio (PAPR) reduction performance mainly depends on the selection of the peak reduction tone (PRT) set and the optimal

All tone reservation methods follow the same concept of A. Tone Reservation PAPR Reduction Method Since for each transmit antenna link there are N r= jK pn K p i jnumber unused subcarriers within the active subcarrier band, then by sending dummy symbols (i.e., symbols not conveying information) in these subcarriers, the PAPR of the OFDM symbol can be reduced. We denote a set of unused [6] and tone reservation (TR) [7], [8]. The tone reservation (TR) technique is an efficient distortionless method and was first presented in [7], [8]. In this approach, a small number of subchannels are reserved to generate peak-canceling signal to reduce PAPR and the signal content at the reserved tones will Tone Reservation is one of them in which a small set of subcarriers are reserved for Peak Cancellation signal.

In this paper, an adaptive tone reservation technique with optimal subcarrier allocation awareness for multi-user OFDMA systems is investigated. In general, a variety of approaches have been proposed to cope with the PAPR problem in OFDM systems. A tone reservation (TR) is an effective technique for reducing PAPR, in which it does not need to transmit any side information and there is no
