Abstract

are a candidate to realize the wide-band ADC for future telecommunication systems. The classical HFB-based ADCs are simulated in both time and frequency domains using simplyrealizable analog filters in this paper. The high sensitivity of HFB to realization errors of analysis filter bank is studied and it is shown that a new HFB architecture is necessary to employ the blind techniques for correcting the analog imperfections. Using the discrete-time model of HFB, a Multiple-Input Multiple-Output (MIMO) model is proposed for the HFB so that a new architecture called subband HFB-based ADC is obtained. The subband HFB ADC not only leads to a better resolution but is less sensitive to realization errors than the classical case. Besides, a Linear-Time Invariant (LTI) system represents the input-output relation of subband HFB without any spectral overlapping in contrary to the classical HFB. Thus, blind techniques may be used for correcting the realization errors in the subband HFB
