Abstract: The embodiments of the present application provide a method and apparatus for modulation recognition of signals based on cyclic residual network, the method comprises: obtaining a signal matrix of a to-be-recognized signal, and extracting real part information and imaginary part information of the signal matrix; generating, according to extracted real part information and imaginary part information, a real-and-imaginary-part feature matrix of the to-be-recognized signal; converting, according to a preset matrix conversion method, the real-and-imaginary-part feature matrix into an amplitude-and-phase feature matrix; and inputting the amplitude-and-phase feature matrix into a pre-trained cyclic residual network to obtain a modulation mode corresponding to the to-be-recognized signal. In the embodiments of the present application, the processing of the to-be-recognized signal is simple and easy to operate, in which neither complex algorithms nor manual processing is required, the flexibility of recognition is high, and the result of modulation recognition of the to-be-recognized signal can be accurately obtained.

Abstract: The embodiments of the present application provide a radar-sensing detection method and device based on radar-sensing communication integration. Said method comprises: when being applied to a sending end, determining a position of a receiving end, then sending a beam control signal to the receiving end through a preset beam control request channel, receiving a beam control response signal sent by the receiving end, and sending a first detection result signal to the receiving end in a preset reservation channel. The embodiments of the present application can expand the detection range of an autonomous vehicle.
