H/sub 2//H/sub /spl infin// signal reconstruction in noisy filter bank systems

Investigates signal reconstruction in the multirate filter bank systems with noisy subband paths. It casts the problem of signal reconstruction into a problem of mixed H/sub 2//H/sub /spl infin// control, and uses the standard results of mixed H/sub 2//H/sub /spl infin// synthesis to design an IIR synthesis filter bank.
