An electronic device, a signal processing method, and a non-transitory computer-readable storage medium are provided. The electronic device includes processing circuitry configured to: phase-adjust a received complex signal according to a compensation phase estimated with a pilot signal; obtaining a receiving bit sequence based on the phase-adjusted complex signal through low-resolution analog-to-digital conversion processing; and demodulating the received bit sequence based on a demodulation neural network obtained by training the pilot signal to obtain a modulation symbol of the received complex signal. According to at least one aspect of the embodiment of the invention, the conversion precision of the low-resolution analog-to-digital conversion unit can be improved at a receiving end by using the compensation phase obtained based on the pilot signal, and the compensation of the mixed distortion is realized through the demodulation neural network obtained based on the pilot signal training ...

The invention discloses a low earth orbit satellite network multi-dimensional resource scheduling method oriented to IoT task unloading, and relates to the technical field of aerospace communication networks. The method comprises the following steps: firstly, calculating a satellite ephemeris according to constellation information of a satellite network, further obtaining visibility and distance of a satellite relative to an Internet of Things device at observation time, and calculating a communication channel gain and a communication time constraint according to the relative position and distance of the satellite and the Internet of Things device; and iteratively solving the joint task unloading and resource allocation problem by using a heuristic algorithm based on the calculated communication channel gain and communication time constraint and the demand condition of the service to be deployed in the network. And finally, performing network resource allocation according to the decision ...
