“…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. However, in this study, the bandwidth size chosen for the F-OFDMA system is 10MHz based on [25]. The entire bandwidth is divided into subchannels, and data symbols are sent in a parallel form.…”

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.

In order to address the shortcomings of orthogonal frequency division multiplexing (OFDM) and extend the lifetime of energyconstrained Internet-of-Things (IoT) devices, the combination of filter bank multi-carrier (FBMC) and simultaneous wireless information and power transfer (SWIPT) is investigated in this paper. Specifically, a multiuser FBMC-based SWIPT system is proposed in which user nodes (UNs) have the capability for both energy harvesting (EH) and information decoding (ID) with the aid of separate antennas. A practical non-linear EH model, which considers the saturation effects of the EH circuit, is considered. The information receiver at both the UNs and base station (BS) adopts an iterative interference cancellation (IIC) receiver to cancel the intrinsic interference in the demodulated FBMC signal. A sum-rate maximization problem is solved to jointly optimize parameters such as time, power, and weight allocations. Sub-optimal schemes are proposed for comparison. Numerical results show that the optimal solution significantly outperforms the sub-optimal methods in terms of achievable sum-rate and amount of harvested energy. Moreover, the results show that the proposed algorithm converges within a few iterations. Index Terms-Filter bank multi-carrier (FBMC), simultaneous wireless information and power transfer (SWIPT), time division multiple access (TDMA), sum-rate maximization, Internet-of-Things (IoT) networks.

Base station (BS) and mobile phones. The (BS) equipment and downlink transmission consume the major energy of cellular networks. One of the promising solutions for decrease Energy consumption (EC) and increasing throughput is the deployment of large antenna arrays that can transmit extremely concentrate beams. In the present work, we propose a new antenna muting scheme for beamforming based on Minimum Variance Distortion Less Response MVDR. The operation of MVDR is based on finding the optimum weight to direct the main lobe beam to the desired user location with a unity gain, Implementation results confirmed that the proposed technique is more efficient than the traditional process of the cellular network.
