(International Islamic University Chittagong, 2024-02) Sifat, Md. Zahidul Islam
Information about the whereabouts of oneself or our cell phones has always been crucial to humans. Technological advancements have supported us across various domains, spanning from interior environments to outdoor global positioning systems. However, achieving real-time indoor positioning has remained a formidable task. The requirement for enhanced positioning has gained prominence in the context of the emergence of 6G cellular networks. The introduction of novel radio technologies, characterized by reduced end-to-end latency, specialized control protocols, and increased processing capacity at the network edge, has opened doors to harnessing the 6G cellular network’s full potential for precise localization in indoor and outdoor settings. Within the 6G cellular network context, this study successfully implemented the classic signal fingerprinting approach using the Received Signal Strength Indicator in a combination with machine learning algorithms. Consequently, it proposed an improved positioning strategy designed for indoor localization scenarios in the next 6G cellular network environment. Using this method, with two datasets, the mean error distance of 0.08025523, meaning an accuracy of 99.92% and 0.10692412 was achieved, which is 99.89% accuracy respectively.

(International Islamic University Chittagong, 2024-06) sajjad, Sajjadul Alam
Analysis of a metamaterial absorber with an S-shaped structure is suggested to reduce the specific absorption rate (SAR) at 3.5 GHz. This absorber exhibits single negative metamaterialcharacteristics and achieves an absorption rate of over 90% for all electromagnetic polarization angles. In the age of 5G, numerous applications are functioning at various frequency ranges, emitting substantial amounts of electromagnetic energy (EM) that possess an elevated SAR value. This radiation has an impact on the human body, specif ically the head and hands, which are exposed to it. In Malaysia, a frequency band of 3.5 GHz has been designated for 5G communication. However, this has resulted in the emission of undesirable signals due to high Specific Absorption Rate (SAR) values. To address this issue, a proposed absorber would beimplemented to reduce SAR levels.

The evaluation of Microstrip antenna performance has changed from a simple free space evaluation, where things like efficiency, gain, bandwidth, and matching were looked at, to a much more complicated process that takes into account the end-user and real-world environments. This process of evaluating is still going on, and both academics and industry people are coming up with better ways to evaluate antennas. This thesis gives new ideas about how to improve antennas parameters. Microstrip antennas have become a part and parcel of today’s mobile communication world due to their low cost, low profile and ease of fabrication in the circuit boards. However, poor performance, such as low power handling efficiency, limited bandwidth, low gain, etc. The next 5th generation (5G) application’s communication will experience significant route loss since high frequency bands will be employed. So, a high gain antenna is necessary for this issue. Since microstrip antennas are small, they are a great choice for 5G technology applications.Therefore, the primary goal of this research project is to create a high-gain & high efficient antenna using a ambient microstrip patch antenna. The antenna operates on the 28 GHz band and was built and tested using CST Microwave Studio. Laminate material is used as a surface close to 2.2 with relative permittivity. Analysis the performance by implementing the MIMO and array. The gain, bandwidth, return loss, VSWR and efficiency of the 1x4 array antenna designed is 9.32 dBi, 9.5 GHz, 34.55 dB, 1.03 and nearly 94% respectively.

Analyzation of Q-factor for Free Space Optical Communication System Using Neural Network There are many options for optical fiber communication system configurations according to user satisfaction, but to establish this system it is essential to simulate the system to avoid unexpected output. To predict the output, among other mathematical tools, many researchers found the neural network is remarkable and one of the most promising methodological approaches to perform network-data analysis and enable automated network self-configuration and fault management. In this research paper, we proposed a neural network to perform optical communications and networking analysis, summarize and compare some classical research using the MATLAB tools.

Cancer prognosis & Survival rate prediction using machine learning algorithm.
(Department of Electronic and Telecommunication Engineering, 2022-10) Alif, Borhan Uddin
Roughly 10 million deaths, or nearly one in six deaths, were caused by cancer in 2020, making it the top cause of death globally. Breast, lung, colon, rectum, and prostate cancers are the most prevalent types of cancer. Any disease that can affect any region of the body is referred to as cancer. Neoplasms and malignant tumors are other words that are used. One characteristic of cancer is the quick development of aberrant cells that expand outside of their normal borders, infiltrate other body components, and eventually move to other organs. This process is known as metastasis. The main reason why cancer patients die is because of widespread metastases [1]. The research was held on two different datasets of breast cancer. To train our model initially we used a primary data set from UCI which includes 569 instances with several attributes [2]. This was for cancer diagnosis prediction/detection. Then we used another dataset that includes 4024 instances with 14 different attributes which we mainly used for death rate prediction with total analysis [3]. Here 6 algorithms were incorporated including KNN, Random Forest, J48, etc., and their results were compared.

The Internet of Things, or IoT, is a network of mechanical and digital computing devices that are networked and have the ability to send data across a network without the need for human or computer involvement. IoT devices are being used more often every day. The addition of 5G technology will increase the responsiveness of IoT devices. As a consequence, a lot of study has been conducted, with researchers offering their ideas for a good antenna design.
