| Abstract: |
| In order to decrease the difficulty of valuable sub-band signals detection and demodulation in multi-channel signals,this paper presents the polyphase structure method and the odd-even channel method to implement the channelized technology of multi-channel signals by analyzing the prototype uniform analysis digital filter bank.Simulation results show that the two methods effectively reduce the algorithm complexity.The odd-even channel method improves the algorithm executable efficiency farther and has been implemented on the hardware platform. |
