Multi input Multi Output (MIMO) communication systems have several advantages in terms of data rate and reliability as compared to Single Input Single Output (SISO) communication systems. A model for SISO and MIMO using multiple point scatterers at mobile station is considered in this paper. A review of some single and multiple antenna configurations and a discussion on using singular value decomposition (SVD) in computing the capacity of MIMO are presented. Numerical results with three individual modes along with their singular values achieved by diagonalization process will also be demonstrated.

Most of the electronic devices used in recent times for various purposes are non-linear type. Hence they produce harmonics which can cause various problems in our modern power system. This research article proposed two active or controlled multipulse AC to DC converters for limiting total harmonics distortion or THD of input AC signal within a standard value. The designed 18-pulse active rectifier shows an input current THD of 8.80% which is very less compared to an 18-pulse passive or uncontrolled rectifier. Proposed another active rectifier i.e. 24-pulse rectifier shows 4.69% of THD of input AC current which can meet IEEE 519 standard requirement for harmonics limitation. Furthermore both of the rectifiers reaches steady state at DC side within a very short time. This also confirms better output power quality of the both designed schemes.

The fast improvement in the telecommunication sector in general and the accompanying revolution in the mobile communication sector provide a challenging task to telecommunication vendors and operators in satisfying the huge subscribers. To address this challenge, appropriate forecasting models must be provided. This study has developed fourteen different single input single output (SISO) Radial basis function neural network (RBFNN) with Levenberg-Marquardt (LM) and Resilient backpropagation (Rprop) algorithms. Two models, Rprop-SISO RBFNN (1-20-1) and LM-SISO RBFNN (1-20-1) were selected based on computational time and minimum values of prediction. When the performance of the models were compared with empirical 4G hourly traffic data collected from an operator in Ghana, Rprop-SISO RBFNN (1-20-1) gave a better computational time while LM-SISO RBFNN (1-20-1) results indicate minimal values of MSE and NRMSE. Therefore LM-SISO RBFNN (1-20-1) model was selected as the appropriate model to predict 4G hourly traffic.

The purpose of a Low Noise Amplifier (LNA) is to amplify received signals to acceptable levels while minimizing noise. The LNA is used in communication systems to amplify very weak signals captured by an antenna. The design of an LNA in Microwave circuits requires a trade-off or careful balance of many important parameters such as Gain, Noise Figure (NF), and Stability. In view of this, it is essential to make calculated choices to realize an optimally functioning LNA. This paper presents a single stage 2.0 GHz LNA optimal design using lumped elements (discrete passive components) for the input and output matching networks. The Radio Frequency (RF) transistor used for this design is the ATF-21170, which is modelled by its Scattering (S) parameters. This is a high performance, low noise Gallium Arsenide Schottky barrier-gate Field Effect Transistor. The LNA is designed using conventional techniques to boost weak cell signals in the frequency range of 1.8GHz to 2.6GHz. The design is done with the aid of Advanced Design System (ADS) 2020 software. The LNA was successfully designed at an operating frequency of 2.0GHz with a gain of 14dB and a minimum noise figure (NFmin) of 0.83dB.

A cryptographic-based encryption algorithm that has low memory and minimal output space requirements as well as involving reduced computational overheads without compromising the strength and security of the encryption is desired for constrained devices in wireless sensor networks. Internet-of-Things (IoT) supports the automated collection and streaming of sensitive data across several other devices through the internet. The insecurity of the internet in supporting communication of critical data between nodes in IoT has been amplified due to the current data breaches and data privacy compromises on such networks in recent times. The paper addresses the challenge of data privacy and integrity breaches among IoT devices with the proposition of a methodology involving a thin cryptographic scheme that combines the Feistel cipher and the MD5 in providing improved security for IoT node data. The results showed an enhanced and fast encryption of data between IoT edge devices and the sink node.

A multiple transmitter coil wireless power transfer system that eliminates the frequency splitting effect as a result of overcoupling between very close transmitter coils is proposed. The use of coils of different sizes in the transmitter array is proposed in order to eliminate the splitting of the magnetic field produced by the transmitters. This is done by designing three different multi-coil transmitter arrays, each with five transmitter coils with a single receiver coil placed 40 cm from the transmitters. The first array is designed with coils of the same size. The second and third arrays are designed with coils of smaller sizes placed between larger size coils. The performance of the three arrays is compared by considering the scattering parameters at the receiver coil. It is shown that using smaller coil sizes between larger coils causes uniform coupling in the multiple transmitter array, resulting in suppression and subsequent elimination of the frequency splitting phenomenon of the received signal.

It is undisputable fact that Coronavirus pandemic will go into the annals of history as one of the devastating plagues. From the healthcare perspective, a lot of efforts are underway geared towards testing, management and vaccination whereas industry and research communities explore innovative solutions. Quite a number of solutions have emerged zooming in on contact tracing, combating misinformation, data aggregation and analysis as well as test result certification with blockchain technology been the core. Aside the reliance on centralized architectures and use of permissioned/consortium blockchain, conspicuously missing in existing solutions based on blockchain is the work around the immutability feature of the technology given the fact that a person’s test result is not static but dynamic. In this paper, we propose a solution using blockchain and smart contract that allows for state changes to be made by authorized entities. We leverage distributed storage technology using InterPlanetary File System (IPFS) for storage of user encrypted records and subsequent retrieval for verification purposes. We extend our solution by incorporating vaccination status to provide comprehensive source of information and show proof of concept. The full code of our proposed solution is made publicly available on GitHub.

Electronic data exchange among edge medical devices often comes with concerns, as data to be transmitted are sensitive and there is the need to protect these valuable information assets to maintain the data integrity and confidentiality. In this paper we propose a scheme that allows edge devices to share medical data securely in a dew-fog computing environment using an AES symmetric encryption scheme of a key length 512-bit and by the hashing of the chosen key using SHA-256 to enhance the security of electronic exchanges.

Among the pandemics that have affected human existence, the Covid-19 virus with uncertain genesis has deracinated the natural structure and cycle of everything around us. Education and especially children’s social life has been jeopardized forcing us to find new ways of doing things in the quest to survive. This study investigated the effect of covid-19 on education from the perspective of primary and high school children staying at home in Ghana. Due to the pandemic, the descriptive study drew respondents across the country using snowball sampling via the internet (social media, email, WhatsApp, etc). Results lead to major conclusions that children employed both manual and/or online methods of learning at home mostly relying on parents’ electronic gadgets and/or computers. They faced mostly issues of bad internet connectivity and expensive data while learning online. Majority (54.6%) claimed they want to resume school amid the pandemic because they mostly miss their friends and teachers and also sometimes needs help studying at home. The strong minority (45.4%) prefer to stay home for fear of infecting their family members. The study recommends an effective but healthy method of educational continuity (small contact hours and online studies) for our youth in this new normal.
