Abstract-There are abundant methods to mitigate PAPR in OFDM signals among which algorithm based tone reservation is of great popularity owing to its low complexity as well as decent BER. Here we have put forward a new distinct algorithm based Tone Reservation technique which is not only less complex and calculates its own threshold as well as PRT signal (unlike other algorithms requiring predetermined threshold and PRT) but also aptly modifies the data by bit by bit comparison with a modified copy of itself (algorithm modified) thus scaling the peaks as and providing a decent BER and good PAPR reduction.

“…In this paper, we consider the selection of the OPRT set for tone reservation [11][12][13][14][15][16][17][18][29][30][31] scheme to reduce the PAPR of an OFDM signal. TR scheme requires a sacrifice in data transmission efficiency because some subcarriers in an OFDM symbol should be reserved as peak reduction tones which are used only to reduce PAPR without carrying data.…”

Tone reservation (TR) is one of the attractive techniques to reduce peak-to-average power ratio (PAPR) in orthogonal frequency division multiplexing system. As conventional TR technique requires exhaustive searching over all the combinations of the given peak reduction tone (PRT) sets, it results in computational complexity that increases exponentially with the number of the subcarriers. In this paper, we aim to obtain a desirable PAPR reduction with low computational complexity. Since the process of searching the optimal PRT set can be categorized as combinatorial optimization with some variables and constraints, we propose a novel scheme, which is based on a nonlinear optimization approach named as invasive weed optimization method, to search the optimal combination of PRT set with low complexity. To validate the analytical results, extensive simulations have been conducted, showing that the proposed schemes can achieve significant reduction in computational complexity while keeping good PAPR reduction. As results of simulations, the proposed scheme shows almost the same PAPR reduction performance as compared with the genetic algorithm-based TR method which has been known to have the best performance and obtains near-optimal PRT sets.

This paper proposed a modified tone reservation (TR) technique that can reduce the peak-to-average power ratio (PAPR) of the orthogonal frequency division multiplexing (OFDM) system and is able to correct errors to avoid channel interference. The TR technique is a widely used PAPR reduction technique, which divides subcarriers of the OFDM system into two sets to generate peak-canceling signals and transmit modulated data. The subcarriers used to reduce the PAPR are called the peak reduction tone sets. The mechanism of peak-canceling signal generation is a primary factor in determining the quality of the PAPR reduction performance of the TR technique. Currently, two signal generation mechanisms exist: TR-gradient-based and TR-clipping-based techniques. Although TR techniques can effectively reduce the high PAPR in the OFDM system, TR techniques lack the ability to correct errors. Therefore, this paper combined block coded modulation codes and TR techniques to provide the modified TR techniques with error correction abilities. From the simulation results, the modified TR techniques had a superior effect on PAPR reduction performance compared with the conventional TR technique. The modified TR technique also possessed the ability to correct errors during signal transmission. 749Numerous techniques improving the high PAPR of the OFDM system have been proposed successively [6], such as amplitude clipping [7], partial transmit sequence (PTS) [8,9], selected mapping (SLM) [10,11], and tone reservation (TR) [12][13][14][15][16]. The amplitude clipping technique adopts the method of filtering signals to reduce the high PAPR. In other words, with a predetermined transmitted signal amplitude threshold, the amplitude clipping technique replaces the transmitted signal amplitude with the threshold when the transmitted signal amplitude is higher than the threshold; conversely, the original transmitted signal is used for transmission when the transmitted signal amplitude is lower than or equal to the threshold. Because the amplitude clipping technique easily induces distortion of transmitted signals, massive calculations must be conducted at the receiving end to improve distortion. Meanwhile, PTS and SLM techniques are categorized as multiple signal representation (MSR) techniques that generate multiple sets of candidate signals, using phase changes during signal transmission and selecting the signal with the minimum PAPR from candidate signals for transmission. Although PTS and SLM techniques can effectively reduce the high PAPR, side information (SI) must be transmitted from the transmission end to the receiving end to identify the candidate signal selected for transmission, thereby facilitating a precise and perfect recovery of transmitted data at the receiving end. The TR technique can also be considered as an MSR technique. However, in contrast to PTS and SLM techniques, the TR technique does not need to transmit additional SI to the receiving end. The TR technique reserves a number of the subcarriers ready to transmit data...
