“…The system parameter applied for this research is based on Table 2. Rayleigh Fading channel is used in this research since it takes into account the effect of propagation environment through the wireless communication medium [26]. The bandwidth used for multiple access systems can be up to a maximum of 20 MHz [19], where the larger the bandwidth, the higher the system's capacity.…”

As modern wireless communication systems move towards 5G implementation, the system must provide sophisticated and ubiquitous service and flexibility. Therefore, Filtered Orthogonal Frequency Division Multiple Access (F-OFDMA) is one of the most suitable modulation techniques used in 5G systems to achieve efficient and reliable wireless communication. Other than that, F-OFDMA also has good quality rather than OFDM since it provides a better result of high side lobes and enlarges the scale of the spectrum analyzer. However, one of the significant problems in the F-OFDMA system is the high peak-to-average power ratio (PAPR), affecting the system's overall performance and causing high transmit power at the transmitter. In this paper, combination of Arithmetic Coding (AC) and Huffman coding (HC) with Asymmetric Numeral Systems (ANS) provide better performance for PAPR as well as bit error rate (BER) in F-OFDMA. Both AC and HC are proposed to combine with ANS and Quasi-Cyclic Low-Density Parity Check (QC-LDPC) since it provides a good result to defeat the high PAPR. BER and PAPR performance were compared for the AC and HC with ANS QC-LDPC. Based on the results, ANS-AC-QCLDPC proved as the best joint method has 35.25% improvement for PAPR while BER has 89.87%. This research also justified that ANS with Arithmetic-QCLDPC and Huffman-QCLDPC give better BER results as well.

“…At a certain width, the system bandwidth is divided into many sub-bands, and each sub-band is then filtered separately [4]. Seem like F-OFDM system basically using OFDM as its core waveform [5,6], this system will also suffer the same issue which is high PAPR value.…”

One of the potential technologies for a future wireless network is filtered-OFDM (F-OFDM). The capacity to handle numerous asynchronous sub-band transmissions is necessary in order to accommodate the diversity of services. However, multicarrier transmission systems with multiple subcarriers transmit signals with high Peak-to-Average Power Ratios (PAPR). The high PAPR value, which results in performance degradation and high-power consumption as a consequence of various distortions, therefore constitutes a significant challenge with the F-OFDM system. In order to obtain improved PAPR reduction, the Cluster Scrambling Codeword (CSC) method and its hybrid precoding approach are developed in this paper, which aims to add to this expanding field of research. This novel concept of the bit-data sequence shifting approach can reduce PAPR more effectively than the traditional scheme. In comparison with the conventional F-OFDM system, the simulation results indicate that the hybrid codeword shifting methodology, CSC+CVMT, achieves a 53.84% PAPR improvement at 4.2dB.

“…Then, the carrier wave will act as a switch in order to create a signal pulse to be modulated. The signal that has been modulated depends on the parameter of the carrier wave such as the amplitude, frequency or phase [14]. The process of digital modulation helps the system to achieve high data capacity, better data security and increase system availability [15].…”

The advancement of mobile communications has rapidly expanded in recent years, with the invention of transmitting and receiving system technology. The use of multiple antennas, also known as Multiple-Input Multiple-Output (MIMO) technology, is a key feature in modern wireless communication systems such as 5G. MIMO utilizes multiple antennas at both the transmitter and receiver to improve the system's performance in terms of data rate, link reliability, and spectral efficiency. In this paper, a block coding technique, was deployed to enhance the reliability of data transmission and introducing redundancy and error correction capabilities. These techniques involve encoding data into blocks and adding redundancy bits, which allow the receiver to detect and correct errors that may occur during transmission. The encoding technique, called the Asymmetric Arithmetic Coder (AAC), and it is supported in 5G system to provide high speed signal transmission in multiple users’ environment. For retrieving a smooth signal at the receiver, a filter was introduced to improve its efficiency of the wireless link. However, the existing filter in the system, caused the increasing of the peak-to-average-power-ratio (PAPR) at the transmitter system. Thus, the block coding technique was implemented to increase the efficiency and reduced the power ratio. The most common block coding technique for wireless communication is AAC technique. The AAC technique was founded to reduce the power ratio and further improve the signal diversity. Recently, for the application of 5G, the AAC was enhanced by adding the number of symbol and improved the PAPR. It is called the Enhancement Asymmetric Arithmetic Coding (EAAC) technique. The EAAC contributes to the lower value of the PAPR. With the use of EAAC as the block coding technique, the transmitter is said to support the system and thus improved the PAPR measurements by 5.5%. Lastly, the reduction of PAPR contributes to minimize the distortion and enhanced spectral efficiency for wireless communication system.
