| 摘 要： | 推导了可直接应用于AD采样数据的高效数字信道化接收机的通用结构，并对抽取因子对信道化输出结果的影响进行了理论分析，得出信道化接收机在不同环境下应用的约束条件。理论分析和仿真结果表明：当信道个数与抽取因子相等时，可实现最小硬件开销的频域无盲区、无混叠的数字信道化接收机。

| Abstract: | A common structure that can be directly applied to AD sampling signals is derived and the effect of the decimation factor on the sub-channel output is also analyzed. The analysis and simulation results show that when the decimation factor is equal to sub-channel number, the best receiver structure without blind-zone and overlap in spectrum domain can be implemented. |
