    The Behaviour of Vertical Bell Laboratories Layered Space-Time Algorithm Combined with Multiuser Detection Schemes in Wireless Communication System
    (Scientific Research Publishing, 2011-05-31) Bamisaye, Ayodeji J.; Ogidan, Olugbenga K.; Osalope, Babatope
    This paper provides the performance analysis of multiuser Vertical Bell Laboratories Layered Space-Time (V-BLAST) system receiver structures for Multiple-input Multiple-Output (MIMO) channel at a base station with assumption of perfect channel estimation and perfect timing delay estimation. In MIMO channels the receivers such as decorrelator, Minimum Mean Square Error (MMSE) and Multistage Parallel Interference Cancellation (MPIC) receiver outperform the conventional receiver. Withal, since the multiple antenna interference led to a strong impact on the performance degradation of a multistage interference cancellation receiver, the performance of MPIC receiver was highly degraded based on system loading.

    Ovulation detection mechanism—a microcomputer based approach
    (Journal Biomedical Science and Engineering, 2011-12) Ogidan, Olugbenga K.; Bamisaye, Ayodeji J.; Adetan, Olawumi
    This paper presents a real-time microcomputer-based logger for measuring basal body temperature (BBT). BBT is the normal resting body temperature of a healthy person immediately upon waking in the morning. The temperature for women normally rises after ovulation due to hormonal changes. The tem-perature is logged real-time into the computer over a period and the BBT chart produced is used to predict ovulation. There is high correlation between the ap-proach developed by this study and other standard measuring equipments—correlation of 0.9945with standard thermistor, and correlation of 0.9977 with standard thermocouple. This development enables privacy of use, allowing women to predict their ovu-lation status at a personal level.
