The peak and the average of SFDR are 89 and 83.5 dB, respectively. The optimal effective number of bits is 11 bit at the Nyquist-rate input, which is equivalent to a figure of merit of 11.7 ...

Abstract: In this brief, we propose a sub-Nyquist frequency estimation method ... To obtain gridless estimation, the overlapping FCs are then reformulated as an finite rate of innovation problem with ...
