    Fingerprint Biometric Authentication for Enhancing Staff Attendance System
    (International Journal of Applied Information Systems, 2013) Oloyede, M. O.; Adedoyin, A. O.; Adewole, K. S.
    Biometric technology that involves the identification and verification of individuals by analyzing the human body characteristics has been widely used in various aspect of life for different purposes, most importantly as regards this study the issue of staff attendance. Despite the numerous advantages of the biometric system and its impact to various work sectors across the globe, most biometric technology users face the issue of defining the right and accurate biometric technology system that will be cost effective in solving particular problems in specific environment. In this paper, a study was conducted using a telecommunication company in the South West region of Nigeria, in order to determine the specific biometric identifier that can be used to enhance their traditional staff attendance system which presently affects the productivity of the organization. The study was conducted using a quantitative approach by designing a questionnaire as the data collection instrument based on different biometric technologies. The survey involved 37 employees based on stratified random sampling technique. The results however show that fingerprint biometric identifier was found suitable for the staff attendance management system of the organization. It therefore, implies that attention should be paid to several factors before recommending biometric technology as a means of improving the productivity of an organization business processes.

    Polynomial based Channel Estimation Technique with Sliding Window for M-QAM Systems
    ((IJACSA) International Journal of Advanced Computer Science and Applications, 2016) Ogundile, O. O.; Oloyede, M. O.; Aina, F. A.; Oyewobi, S. S.
    Pilot Symbol Assisted Modulation (PSAM) channel estimation techniques over Rayleigh fading channels have been analysed in recent years. Fluctuations in the Rayleigh fading channel gain degrades the performance of any modulation scheme. This paper develops and analyses a PSAM Polynomial interpolation technique based on Least Square (LS ) approximations to estimate the Channel State Information (CSI) for M-ary Quadrature Amplitude Modulation (M-QAM) over flat Rayleigh fading channels. A Sliding window approach with pilot symbol adjustment is employed in order to minimize the computational time complexity of the estimation technique. The channel estimation performance, and its computational delay and time complexity is verified for di erent Doppler frequencies ( fd), frame lengths (L), and Polynomial orders (P-orders). Simulation results show that the Cubic Polynomial interpolation gives superior Symbol Error Rate (SER) performance than the Quadratic Polynomial interpolation and higher P-orders, and the performance of the Polynomial estimation techniques degrade with increase in the P-orders.
