Abstract

In order to solve the problem of inflexible parameter settings in traditional dynamic channelization structure, a weighted overlap-add (WOLA) filter bank is proposed to implement dynamic channelization structure. The filter bank is deduced and emulated through MATLAB. The simulation results show that the WOLA dynamic channelization structure enhances the flexibility of parameter setting and the reconstruction error is within 5×10-3. Comparing with the Discrete Fourier transform (DFT) polyphase filter structure, the system reconstruction error is reduced by an order of magnitude, it is verified the feasibility and good reconstruction characteristics of the WOLA dynamic channelization structure.
