摘　　要：通常的数字信道化方法,由于信道不重叠,相邻信道之间存在盲区,当信号落入盲区时,会造成信号畸变甚至丢失。利用信道重叠技术可以有效地解决信道之间的盲区问题,但需要研究高效算法。文中根据一般数字信道化高效算法的数学推导思路,推导出通带重叠的数字信道化的高效算法,并建立了算法模型,从而解决了无盲区数字信道化的高效实现问题。利用Matlab建立仿真模型,仿真结果验证了模型的正确性。Blind zones exist between the neighbour channels after the usual digital channelization. When their fall into the blind zones, the signals would be distorted or even lost. This problem could be solved by using pass-band overlap, and it in accordance with the thinking IS of necessary to find an effective algorithm. The effective algorithm is devised usual digital channelization, and the algorithm model is built. The simulation results show that the model is correct.
