摘要
提出了一种基于双速率欠采样的宽带数字信道化接收机,该系统采取数字信道化与双速率欠采样相结合的方式来实现在较小采样速率下对大带宽信号检测,同时由于在较小采样速率下能够选取高位数的ADC器件,因而也能够提高数字信道化接收机所能适应的信号瞬时动态范围。通过计算机仿真验证了所提接收方法的正确性。
A new kind of digital channelized receiver is proposed, which is based on double sub- Nyquist sampling technology and digital channelized technology. Wide bandwidth signals could be detected by this system, while the transient dynamic range of the receiver can be improved with analog digital convertor （ADC） when high bits are selected. The simulation results show validity of the receiver.
