MATLAB code to test SPIM approach for SS

MATLAB code for test spectrum sensing algorithm based on statistical processing of instantaneous magnitude (SPIM). The associated SCRIPTs allow: Generating different signals to check the method, FHSS, LFM, CW Pulse, etc. Plot the generated signal, the detection threshold and compare it with the ideal detection. Determine the errors for the different hypotheses based on SNR. Calculate errors in the determination of the amplitude and frequency for different SNRs. Evaluate the probability of detection with different threshold control values A and U. Compare the errors in detection for the SPIM method and the energy detector. Plot the values of the TPR FPR rates to calculate the ROC curve. Determines the MAD PDF of the instantaneous phase and the average instantaneous amplitude for comparison.
