Abstract: Until now, most Reversible data hiding (RDH) techniques have been evaluated by Peak signal-tonoise ratio (PSNR), which based on Mean squared error (MSE). Unfortunately, MSE turns out to be an extremely poor measure when the… read more here.

DOI: 10.1109/tsp.2017.2715010
Abstract: This paper considers unimodular sequence synthesis under similarity constraint for both the continuous and discrete phase cases. A computationally efficient iterative algorithm for the continuous phase case (IA-CPC) is proposed to sequentially optimize the quadratic… read more here.

DOI: 10.1186/s13634-016-0440-1
Abstract: In this paper, a procedure for the null broadening algorithm design with respect to the nonstationary interference is proposed. In contrast to previous works, we first impose nulls toward the regions of the nonstationary interference… read more here.
