The objective of this correspondence is to design a fixed-order H2 optimal inverse filter of a given periodic FIR digital filter for signal reconstruction in the presence of measurement noise. The problem is converted to time invariant H2 optimization by applying the lifting technique for periodic filters and solved using the linear matrix inequality (LMI) approach.
