“…Where N is the number of subcarriers and V is the number of sub blocks. Now all the positions of subcarriers are set to zero which are occupied in another block [10], this gives the X m = ∑ V k=1 X m k . After this a constant phase rotation of p mk = e j фmk is applied to each sub block where ф mk ϵ [0, 2Π] , 1< k < V. The phase rotation is not applied on first block which is constant.…”

Despite the fact that OFDM has numerous features, the high peak-to-average power ratio (PAPR) deems one of the challenging disadvantages face by the system in the real applications. The high PAPR limits the OFDM signal efficiency on the transmitter side. Thus many PAPR alleviation approaches have been suggested in the past. Partial transmit sequences (PTS) has been accounted as one of the successful procedures for decreasing the high PAPR; with the consideration that the computational complexity of the PTS method regarded high relatively. Moreover, improving the PAPR mitigation performance of the PTS algorithm relies upon the number of the partitioned subblocks, the number of the phase rotation vectors, and the kind of the segmentation scheme utilized. This article presents new segmentation schemes to enhance the PAPR mitigation execution without further intricacy on the system. Adjacent shifting segmentation scheme (Ad-Sh-PTS) and rows exchange of interleaving segmentation schemes (IL-Ex-PTS) are proposed depending on the two well-known segmentation schemes of adjacent partition PTS (Ad-PTS) and interleaving partition PTS (IL-PTS). The simulation demonstrates that the suggested algorithms can accomplish mitigation in PAPR preferable compared to the traditional schemes, Ad-PTS and IL-PTS schemes.

“…This is because of the OFDM system provides many advantages such as its robustness to multipath fading, immunity to inter-symbol interference (ISI), the ability for high data transmission rate, and bandwidth efficiency [1] [2] [3] [4]. OFDM system has been considered as a multiplexing technique for many digital communication systems such as wireless local area network (WLAN) IEEE.802.11a/b/g/n [5], worldwide interoperability for microwave access IEEE.802.16 [6], digital video broadcasting (DVB) [7], and digital audio broadcasting (DAB) [8]. Also, OFDM system is used in LongTerm Evaluation (LTE) which is the standard for the fourth generation (4G) technology [9] [10].…”

Abstract-Although the orthogonal frequency division multiplexing system (OFDM) is widely used in high-speed data rate wire and wireless environment, the peak-to-average-powerratio (PAPR) is one of its major obstacles for the real applications. The high PAPR value leads some devices of the OFDM system such as power amplifiers and analog to digital converters to work out of band of these devices. Thus the system efficiency is degraded. Many techniques have been proposed to overcome the high PAPR in OFDM systems such as partial transmit sequences (PTS), selected mapping and interleaving technique. PTS is considered as one of the effective PAPR reduction methods; this scheme depends on segmentation of the input data into several subblocks and then combined again. The three well-known segmentation schemes are pseudo-random, adjacent and interleaving; each scheme has PAPR reduction performance, and computational complexity differs from one to another. In this paper, five types of segmentation schemes are proposed to improve the PAPR reduction execution including sine and cosine shape as well as hybrid interleaving and adjacent schemes in new approaches. From the simulation results, the proposed methods can achieve PAPR reduction performance greater than that of the adjacent and interleaving partition schemes, without increasing the computational complexity of the system. Moreover, the enhanced schemes can realize better PAPR performance with any number of subcarriers.
