New innovative technology such as unlicensed wireless connectivity has become essential to provide more beneficial and advanced services. Therefore, it is necessary to study the use of broadband available and potentials of spectrum harmonization for massive unlicensed applications, equally Wireless Fidelity (Wi-Fi) with higher frequency and wider bandwidth. This paper presents an interference assessment between unlicensed Wi-Fi service and an incumbent service such as Outside Broadcasting (OB) system in the 6 GHz band. It also includes several radio interference scenarios to analyse coexistence by Minimum Coupling Loss (MCL) and Monte Carlo (MC) methods. Consequently, this study suggests protection distance as a possible approach for the coexistence of the unlicensed Wi-Fi service and OB system in the 6 GHz band.

Broadband slotted circular patch antenna with Defective Ground Structure intended for Ku band satellite communications is presented in this communication. The proposed antenna has a fundamental circular radiating element in which a square ring slot is etched along with a circular slot inside it. The ground is etched with a rhombus ring slot at the center and square slots in the corners. The defective ground provides multiple frequencies of operation and the slots in the radiating element act as filters combining the multiple frequencies of operation into broadband. The antenna is fabricated on an FR4 substrate with a volume of 40mm×48mm×1.59mm and a dielectric constant of 4.4. The antenna has been excited using a stripline feed of 50Ω impedance. The proposed antenna has an impedance bandwidth of 1.87GHz ranging from 13.61GHz to 15.48GHz with gain and directivity of 2.2dB and 6.09dB at 13.84GHz, 2.8dB and 5.47dB at 14.48GHz, respectively. The simulated and measured antenna results are in good agreement, showing that the proposed techniques enhance the antenna bandwidth.

This research work explores the Levenberg- Marquardt training algorithm used for Artificial Neural Network (ANN) optimization during training and the Bayesian Regularization algorithm for the enhanced generalized trained network in training a designed non-linear vector median filter built on Multi-Layer Perceptron (MLP) ANN called model-1 and a conventional MLP ANN called model-2. The model-1 employed in the design helps in dataset de-noising to ensure the removal of unwanted signals for the improved training dataset. An early stopping method in the ratio of 80:10:10 for training, testing, and validation to overcome the problem of over-fitting during network training was employed. First-order statistical indices, the standard deviation, root mean squared error, mean absolute error, and correlation coefficient were adopted for network training analysis and comparative analysis of the designed model-1 and model-2, respectively. Two locations, Line-of-sight (location-1) and non-Line-of-Sight (location-2), were considered where the dataset was captured. The training results from the two locations for the two models demonstrated improved prediction of signal power loss using model-1 in comparison to model-2. For instance, the correlation coefficient, which shows the strength of the predicted value to the measured values (closer to 1) establishing a strong connection, gives 0.990 and 0.995 using model-1 for location-1, training with Lavenberg-Marquardt and Bayesian Regularization algorithm, respectively and 0.965 and 0.980 for model-2 using the same algorithms. It is seen that the Bayesian regularization algorithm, which optimizes the network in accordance with the Levenberg- Marquardt algorithm, gave better prediction results. The same sequence of improved perditions using designed model-1 in comparison to model-2 were seen with training results in location-2 while also adopting other employed 1st order statistical indices.
本研究探索了用于人工神经网络(ANN)训练优化的Levenberg- Marquardt训练算法，以及用于增强广义训练网络的贝叶斯正则化算法，用于训练基于多层感知器(MLP) ANN (model-1)和传统MLP ANN (model-2)的非线性向量中值滤波器。设计中使用的model-1有助于数据集去噪，以确保对改进的训练数据集去除不需要的信号。为了克服网络训练过程中的过拟合问题，采用80:10:10的训练、测试和验证提前停止方法。采用一阶统计指标，标准差、均方根误差、平均绝对误差和相关系数分别对设计的模型-1和模型-2进行网络训练分析和对比分析。两个位置，视距(location-1)和非视距(location-2)，被认为是捕获数据集的位置。两种模型的两个位置的训练结果表明，与模型2相比，使用模型1可以更好地预测信号功率损失。例如，相关系数表明预测值与实测值之间的强度(更接近于1)建立了较强的联系，使用Lavenberg-Marquardt和Bayesian正则化算法对location-1进行训练，使用model-1分别给出0.990和0.995，使用相同算法对model-2进行训练，分别给出0.965和0.980。可以看出，根据Levenberg- Marquardt算法对网络进行优化的贝叶斯正则化算法给出了更好的预测结果。与模型2相比，使用设计的模型1改进条件的序列与位置-2的训练结果相同，同时也采用了其他一阶统计指标。

Today, high data rate is the prior requirement to support services and applications. It is definitely a challenge for the 5G New Radio (NR) in providing high data rates, in order to support use cases, especially enhanced Mobile Broadband (eMBB). The objective of this research is to design a 5G network which has greater data rates employing carrier aggregation techniques. Carrier Aggregation (CA) is a way which is able to improve data rates by aggregate component carriers, hence, it can make a wider bandwidth. There are three modes of CA scenario that can be used: intra-band contiguous CA, intra-band non-contiguous CA, and inter-band noncontiguous CA. In this research, the 5G network planning with carrier aggregation on inter-band employing bandwidth 40 MHz at frequency 2300 MHz and bandwidth 100 MHz at frequency 3500 MHz was simulated in Mentum Planet software. The simulation implemented at Marunda Center Industrial Area in Bekasi used downlink outdoor-to-indoor (O2I) with Line of Sight (LOS) scenario. The parameters analyzed in this research employed three main parameters: SS-RSRP, SS-SINR and data rate, which resulted CA SS-RSRP increased by 0.14%, SSSINR increased by 4.48%, and peak data rate increased up to 1412.26 Mbps from 312.872 Mbps

The emergence of IoT opened new opportunities for development in various fields. With all the information that it gathers, it became an interesting target for multiple attackers. Thus, this study will enforce security solutions to IoT-based devices specifically in the perception layer by incorporating a Temperature Comparison Test, Keyed Hash Algorithm and evaluating it using SPRT especially in the defense against malicious activities detected in the nodes of a network namely for Mobile and Immobile attacks. For immobile attacks, using the keyed hash algorithm and the SPRT, the hash key of the passcodes was compared to determine the safety of the nodes. Hence, from the functionality test that was conducted, and evaluating the data gathered using SPRT and Bernoulli’s equation, the reliability of the protocol to detect Immobile attacks is concluded to have a 100% detection rate. For mobile node attacks, the study assumes the environment to be under normal, warm, and cold room temperatures. where both mobile and without mobile attack is simulated, the result shows that there is only an overall 3% difference from the temperature measure by the sensor to the ambient temperature. Hence, combining these protocols that are applied in the study eliminates the single points of failure in the nodes that are either applicable only to a distributed scheme or mobility support, the study also compared the tested protocol to the other existing protocols.

A MIMO-OFDM wireless communication technique possesses several advantages accrued from combining MIMO and OFDM techniques such as increased channel capacity and improved BER performance. This has made the technique very amiable to current and future generations of communication systems for high data-rate transmission. However, the technique also inherits the high PAPR problem associated with OFDM signals—a problem still requiring a practical solution. This work proposes a PAPR reduction algorithm for solving the problem of high PAPR in MIMO-OFDM systems. The proposed method uses a low-complexity signal mixing concept to combine the original transmit signal and a generated peak-cancelling signal. The computational complexity of the proposed method is O(M) , which is very much less than O(N log2 N) of the FFT algorithms. This is because M, which denotes the number of nonzero peakcancelling samples, is much less than N, the FFT window size. The proposed method was found to achieve high PAPR reductions while utilizing only a few nonzero peak-cancelling samples and it does not significantly change the power of the transmitted signal. For example, with M=5% of 256-point IFFT samples, corresponding to a data rate loss of 4.8%, a large PAPR reduction of 5.9 dB could be achieved at a small power loss of 0.09 dB. Compared with other methods proposed in literature, the proposed method was found to outperform them in terms of PAPR reductions and BER performance.
