摘　　要：为了满足通信信号筛选的需要,文章对FIR滤波器的实现方式进行了改进。根据通信信号在频域所处的频带范围,算法仅仅需要简单的数学运算,就可在线任意连续调整滤波器的通带范围,以满足信号筛选的需要。实验结果表明:该算法可以在频域快速、灵活的筛选信号,可应用于各种盲信号采集与处理的场合。In order to meet the requirement of communication signal sorting, the way to realize FIR filter is optimized. According to sub - band that the interested signal lie in, the pass band of sorting filter can be changed online by simple operation within the capability of FPGA. Experiment results show that, the algorithm can sort the signal in frequency domain in time with much flexibility, and it can be used to solve various blind signal collection and processing problems.
