Figure 6From: Joint multiband signal detection and cyclic spectrum estimation from compressive samplesThe process of spectrum sensing in the first step of CS-FAM. (a) The spectrum of original multiband signal, SNR = 0 dB. (b) The results of d computed by SOMP algorithm. (c) The decision results with the constant false-alarm detector. (d) Eliminate the false spurs by bandwidth constraint.Back to article page
