Abstract

In the project a smart antennas assisted wideband spectrum mobile user detection algorithm for cognitive radios is simulated. In this approach, the wideband spectrum sensing issue is transformed into estimating the number of occupied channels based on the Hannan-Quinn (HQ) criterion, and then determining the occupancy status for each channel by the sample power. The power spectrum is computed by finding the eigen values of the HQ criteria and then finding out the L-M eigen values and there corresponding eigen vectors. Then the eigen vectors are used in determining the power spectrum of the signal whose peaks will give information about the spectrum occupied by the mobile user.
