Graduate School of Infomatics, Kyoto University
Abstract The design procedure for digital communication systems is developed based on thesampled-data H ∞ control theory. The procedure provides transmitting/receiving filters, which
optimize an analog otimal performance. Furthermore, the trade-off between the attenuation of thereconstruction error and the energy of the transmitting signal is considered by the H ∞ design with
an appropriate weighting function. Numerical examples are presented to illustrate the effectivenessof the proposed method.
