Abstract

The ever increasing demand for wireless broadband services has imposed severe bandwidth constraints on wireless communication system. This challenge has necessitated the emergence of cognitive radio technology that implements the dynamic spectrum access for spectrum utilization by sensing and using the underutilized spectrum on co-primary basis without interference to the primary users. In this paper, an energy-based, nonparametric spectrum sensing algorithm was proposed and implemented in MATLAB. The consistent TV signal estimation was done by Blackman-Tukey windowing. The result showed the PSD in terms of dB and dBm of the free, busy and interfered instantaneous TV channels at UHF range from channel 21 through channel 69. The detectable TV signals’ threshold was set to be at -114 dBm and RxLEV of the TV channels showed channel number 46 with about -117 dBm to be the best candidate channel for TVWS applications at that simulation time..

Key Words
