Example Embodiment
[0020] The present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0021] like figure 1 As shown, a system for generating a true random sequence includes a receiving antenna 1 capable of receiving radio signals from space, a low-noise power amplifier 2, an automatic gain controller 3, an A / D converter 4, and a central processing unit 5. The receiving antenna 1 is sequentially connected to a low noise power amplifier 2 , an automatic gain controller 3 , an A / D converter 4 and a central processing unit 5 , and the central processing unit 5 is connected to the automatic gain controller 3 under control.
[0022] The low-noise power amplifier 2 is connected to the automatic gain controller 3 through a band-pass filter 6, which can filter out spurious and interference signals outside the pass-band.
[0023] The central processing unit 5 adopts an FPGA processing module, and the curre...
