Item Dynamic optimization of soft handoff thresholds of a base transceiver station in CDMA networks(Department of Electrical Engineering, Ahmadu Bello University, Zaria., 2011) Opadiji, Jayeola; Ayeni, Adeseko; Oyeniyi, Yetundework presents a dynamic optimization protocol which is aimed at improving the performance of a cell in a CDMA network during call handoff process by reducing the number of dropped calls. The protocol responds to a changing number of call requests in a cell by adjusting soft handoff thresholds in such a way as to minimize call drops. The optimization model and a Genetic Algorithm (GA) based solution to the dynamic optimization problem are presented. Original simulation programmes were written in Java and results from simulations performed using the proposed method and the existing handoff protocol based on static preprogramming of the threshold values show that the proposed method outperforms the existing method.Item Improving pedagogy in a digital signal processing course using computer-Aided learning systems(Published by IEEE Nigeria, Computer Science Section., 2011) Opadiji, Jayeola; Ajiboye, Aye; Ayeni, Adeseko; Olatunji, SamuelThe development and deployment of a computer-aided learning tool which serves as a learning aid for undergraduate course in digital signal processing is presented. We have carefully outlined the construction of the algorithm and the implementation process of the software with the aim of improving the level of understanding and assimilation of the concepts that make up the course. It also inspires software development at undergraduate level. Although the scope of this project was limited to fundamental principles of Digital Signal Processing, it was found to inspire software development among undergraduate students.Item Spectral Limitations and the Emerging Trends in Wireless Communication(University of Ibadan Journal of Science and Logics in ICT Research, 2020-05) Ayeni, Adeseko; Onidare, Samuel O.; Sowande, Olugbenga A.; Adebowale, Quadri I.The electromagnetic spectrum had long been found to support the transmission of information. In this paper, the authors provided a brief treatise on the stupendous growth of wireless communication appeal, as an alternative to wired communication, for long-distance communication. Specifically, the paper delved into how the radio portion of the electromagnetic spectrum emerged to support the transmission of information. A discussion of the profound progress that had been made in the field of mobile communication with the emergence of different generations leading to the, now, proposed 5G networks, with increasing capabilities intended to make life more meaningful in all areas of human endeavour, was also provided. Further consideration was provided on the finite nature of the radio spectrum, which became a challenge in the face of the consistently emerging wireless technologies and rapid deployment of such emerging technologies to match the exponential increase in transmittable information types and demand for such. The inadequacy of the traditional spectrum management approach, the fixed spectrum allocation, which, partly, accounts for the “scarcity of the radio spectrum” that accompanied the wireless communication growth was expounded. Finally, the various efforts made to confront these challenges and the techniques involved in the new approach to spectrum management; i.e. the dynamic spectrum access or sharing was discussed
