Multirate filter bank reconstruction of bandlimited signals from bunched samples

A method for reconstructing a bandlimited signal from its periodic bunched samples is presented. As in prior approaches, a multirate filter bank structure is used to reconstruct the signal; however, the technique used to design the reconstruction filter bank is different. The solution presented employs an interpolation filter to model the signal at the input of the reconstruction filter band. FIR synthesis filters are selected to reduce aliasing and distortions of the reconstructed signal. Simulation results showing the quality of reconstruction are presented.
