Problems solved by technology

When the power of the useful signal is small and the signal is weak, the signal-to-noise ratio of the useful signal is low due to the influence of noise, which cannot satisfy the Nyquist sampling law, so that the waveform of the analog signal cannot be completely restored, and the complete useful signal cannot be obtained.

Abstract

The invention provides a method for processing a microwave signal and a receiver. The method comprises the following steps of: receiving the microwave signal; dividing the microwave signal into multiple paths of signals; detecting the multiple paths of signals by using a plurality of microwave quantum detectors to obtain output results of the plurality of microwave quantum detectors; and determining information bits in the microwave signal according to the probability distribution of the output results of the plurality of microwave quantum detectors. According to the method, the information bits in the microwave signals are judged by using the coherence characteristics among the microwave quantum detectors, the detection of useful signals can be completed under the condition that the microwave signals are weak, and the sensitivity of microwave signal detection is improved.

Description

technical field [0001] The present application relates to the field of communications, and more particularly, to a method and receiver for processing microwave signals. Background technique [0002] In the field of communication, it is often necessary to process wireless signals, for example, the reception of microwave signals. [0003] The reception of microwave signals needs to complete the conversion from analog signals to digital signals, but the Nyquist sampling law must be satisfied during sampling to completely restore the waveform of analog signals. When the power of the useful signal is small and the signal is weak, the signal-to-noise ratio of the useful signal is low due to the influence of noise, which cannot satisfy the Nyquist sampling law, so that the waveform of the analog signal cannot be completely restored, and the complete useful signal cannot be obtained. Information. Contents of the invention [0004] The present application provides a method for pr...
