“…The model is performed in the OFDM system when the subcarrier number is 1024 and the constellation order M=265. In this work, the method compared and simulated by PTS, SLM, interleaving, Pushkarev's method [17], Singh's method [24], Tiwari's method [22], Duanmu's method [30], Wang's method [37], and Xiaoqiang's method [27] when V=4, U=24, K=11, W=4. The SLM-CSS-PTS method outperforms other methods in terms of PAPR performance reductions.…”

“…At the OFDM system, the signal output is composed of summing several different modulated subcarriers as a sinusoidal form. Due to the nature of the IFFT unit, the instantaneous peak power of some subcarriers of the sinusoid signal may be added together to become much larger than the average power of the signal [30]. Exactly, PAPR in decibel (dB) can be formulated as [31] as (2).…”

The orthogonal frequency division multiplexing (OFDM)-4G and 5G filter technology suffer a drawback that represents the direction of the peak average to power ratio (PAPR) in orthogonal frequency division multiplexing due to the nonlinear nature of the transmitter. There are a lot of traditional and hybrid methods of these traditional methods to reduce the harmful high PAPR value. Newly, several new hybrid methods have been adopted to reduce PAPR but it faces an increasing level of computational complexity in the system. In this paper, two important and effective conventional methods for reducing PAPR are studied, analyzed, and investigated for the hybrid pathway which is the incorporation of selective mapping (SLM) method and partial transport sequencing (PTS) method, which achieve increased efficiency of PAPR reduction while computing the computational complexity of each method. The method depends and balances with computational complexity. The search is based on multi-carrier connections such as multi carrier-code division multiple access (MC-CDMA) and OFDM.

“…After each simulation configuration to make sure that it meets all the requests, designers can generate multiple netlists simulation hierarchy and each validates them on their own or downloaded on the simulator to simulate different combinations of modules that can exist during the operation of the machine [89]. [89] Implementation of PR in the field of communications will allow the user to design, build, test, implementation of communication modules in a few minutes instead of a few hours on the FPGA [90].…”

Software Defined Radio (SDR) has the flexibility to modify the characteristics of the receiving and transmitting radio device, without physically adjusting the hardware, due to development in the system. Because of the increasing need for wireless communication applications so as to enable consumers to communicate anywhere through information led to the emergence of many communication devices to include the large amount of applications that every one of the devices needs power and thereby increase the total power. This study confirms that the wireless communication system for secured transmit data, fast and inexpensive; can be done by implementing using Partial Reconfiguration (PR) modern technology in FPGA developing based on SDR. The Speed and performance can be improved. The area also can be decreased. The new Xilinx, Vertex Series FPGA, provides the provision of PR. The power consumption can be reduced by applying power reduction techniques in the blocks. The combination of MATLAB (Simulink and M-file) and Simulink HDL Coder offers flexible capabilities for analysis, design; simulation, implementation, and verification. With all these capabilities, in a single system to reduce the time spent tuning for reducing the algorithms and models during rapid prototyping and experimentation and less time on HDL coding. Contribution/ Originality: This study contributes in the existing literature review for implementing MC-CDMA wireless communication system using Partial Reconfiguration (PR) that is a new technology in FPGA. 1. INTRODUCTION The wireless communications revolution started with the mobile phone at the beginning of the 80's and all the improvements which have led to the multiplication of mobile and wireless communications networks and standards [1]. The 1st Generation (1G) of technology was characterized by analog means voice only; 1G quality was too low and also had connections to low speed, but they effectively offered the inherent easiness of mobile communications. The system used in 1G was Frequency Division Multiple Access (FDMA) [2]. The 2nd Generation (2G) of technology is digital in the United States, most of the devices and services were digital. The spread of digital mobile
