A Wide- Band Signal Reconfiguration Method Based on Improved Channelized Architecture

Digital channelized technique is widely applied on the wide- band signal processing area. As the number of channels equals to the decimating factor( also inserting factor),classic channelized structure has to face the aliasing issues from the overlapping channels,which employs great distortion for the wide- band signal receiving and reconfiguration. An improved channelized structure is proposed,which also deduces the poly- phase filter banks algorithm. Finally the simulation by Matlab shows the method has an excellent result.
