Adaptive and Blind Wideband Spectrum Sensing Scheme Using Singular Value Decomposition

Pseudocode 1

Pseudocode of ABRMB scheme.

Input: Observation matrix , compressed sampling signal , reconstruction error , tuning

parameter of the potential of spectral support, maximum iteration .

Initialization: .

Pretreatment:

(1) Noise intensity estimation: .

(2) Sparsity order estimation:  (,  ), .

(3) The number of sub-bands: .

Iteration:

While  

(1) Random projection and dimension reduction: , .

(2) Solver solution: , .

(3) Storage of spectral support: .

(4) Obtain the estimation and calculate the residual: ,

.

(5) Condition test: If

Break;

End

(6) .

End

Until the end of the iteration, condition (5) is not satisfied, then make the best selection:

If

.

End

Output: return support
