摘　　要：针对群信号中有用子信道信号检测和解调难度较大的问题,通过分析均匀数字滤波器组分析器的基本型,提出了将多相结构和奇偶分路应用于群信号信道化技术的方法。仿真结果表明,这两种方法都有效降低了算法复杂度,而奇偶分路法进一步提高了算法的运行效率,目前已通过硬件实现。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.
