摘要
通常的数字信道化方法,由于信道不重叠,信道之间存在盲区.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,建立了算法模型,从而解决了信道之间的盲区问题.仿真结果验证了模型的正确性.
Because channels do not overlap, blind zones exist between the neighbour channels after the usual digital channelization. Channelizing algorithm with passband overlap is achieved based on the deduction method of the usual digital channelization, and an algorithm model is built. The simulation results show that the model is correct.
