The artificial spectrum scarcity has been created irrespective of the geographic allocations, frequency and time due to the over-crowed unutilized allocated licensed frequency bands. to avoid this underutilization of the spectrum we have focused, firstly, on the spectrum sensing techniques. however, various sensing techniques arc prevailed in the wide-range of literature. The propose a novel hybrid dost based fast spectral estimation for cognitive radio systems to enhance the performance of the spectral estimation of the cognitive radio systems in the presence of fading environment.
