    (2017 IEEE 3rd International Conference on Electro-Technology for National Development (NIGERCON), 2017-11) Sikiru, Ismaeel Abiodun; Faruk, N.; Popoola, S. I.; Imam-Fulani, Yusuf Olayinka; Oloyede, A. A.; Olawoyin, L. A.; Surajudeen-Bakinde, N. T.
    Explosion in the demand for mobile applications those obtained based on actual measurements of the noise floor overestimates the occupancy values across all bands while the GSM 900 and 1800 MHz bands in Ilorin, Nigeria to cover a though, the International Telecommunication Union (ITU)has are examined.Spectrum measurements were conducted in the optimum prediction, 5dB above the measured average noise level should be considered as detection threshold. Furthermore, it was ITU 10 dB was found to be too conservative. Therefore, for and services necessitates the efficient utilization of the limited acceptable threshold value. In this paper, the effects of energy detection threshold techniques on duty cycle in the GSM bands provided a benchmark of 10dB above the noise level as an found that the number of frames of the sensing data do not have analytical method of determining noise level (theoretical) and most appropriate threshold value is not yet clearly stated, bandwidth of 105 MHz. Experimental results based on radio spectrum. Determination of a suitable detection threshold the probability of false alarm or failure detection. However, the Inappropriate choice of the threshold value may either increase is an important aspect of spectrum occupancy measurement. (measured) were analyzed. Findings indicated that the MaxNoise significant effect on the duty cycle
