摘要
为满足高效、低复杂度数字信道化结构的需要,提出了一种基于人工蜂群算法的频率响应屏蔽(frequency response masking,FRM)信道化设计方法。该方法将FRM与数字信道化窄过渡带滤波器组相结合,降低了计算复杂度及工程实现难度。推导了基于人工蜂群算法优化的FRM信道化结构,通过仿真验证了该设计的正确性,并对信道化优化结构进行了FPGA硬件实现。通过与经典FRM信道化结构性能进行对比,验证了基于人工蜂群算法的FRM信道化结构具有更低的资源消耗与时延。
In order to meet the requirements of high efficiency and low complexity of digital channelized structure,artificial bee colony algorithm based on frequency response masking(FRM)channelized design method is proposed.FRM is combined with digital channelized narrow transition band filter banks in the method,which reduces the computational complexity and engineering implement difficulty.FRM channelized structure optimized based on the artificial bee colony algorithm is deduced,and the correctness of design is verified by simulation.The channelized optimization structure is implemented by field programmable gate array(FPGA),and the performance of channelization structure is compared with the classic FRM channelization structure.It is verified that FRM channelized structure based on artificial bee colony algorithm has lower resource consumption and delay.
