The invention discloses a vehicle-mounted electrical control unit (ECU) debugging simulation system and method based on digital twinning. The system is composed of a data aggregation and time reference module, a consistency evaluation module, a synchronization and correction module, a semantic communication and scheduling module, an arbitration and security debugging module, and a cross-layer adaptive degradation and execution and iteration module. Channel-level time delay is estimated through a unified time reference, a consistency difference spectrum containing amplitude, time sequence, event and derivative components is constructed, confidence is given, time delay compensation and event-level alignment are calculated, and deterministic and priority scheduling is implemented according to semantic benefits; actions such as parameter recharge, message injection, task rhythm perturbation and environmental stimulation are generated and limited under the constraint of a security invariant set, control right soft handover and gating are realized based on confidence, and grading and degrading are performed when the confidence is low or the constraint is triggered; millisecond-level bidirectional collaborative debugging of twin and physical ECUs is realized, and consistency convergence, safety and bandwidth time arrival are improved.

Embodiments relate to a method and apparatus for a soft satellite handover procedure. A method for a user equipment (UE) to communicate with a source satellite to switch to a target satellite includes the operations of: receiving a signal from the source satellite; and determining whether to handoff to the target satellite based on hard handoff or soft handoff.

The application relates to a signal processing method, device, system, storage medium and program product. The method comprises the following steps: for any next-level device, determining the AGC gain corresponding to the next-level device according to a preset threshold and the uplink power of the current uplink signal of the next-level device, and performing gain adjustment on the target uplink signal of the next-level device according to the AGC gain, so as to realize automatic gain control. The method is not only beneficial to reducing uplink combined noise, improving the SNR of the uplink signal of the communication interface and the dynamic range of the signal, thereby improving the uplink rate of the entire cell in the coverage area, but also saves the traffic judgment process, and does not need the corresponding carrier soft switching process of the AU device, so that the signal processing method of the embodiment is more efficient and simple.

The application discloses a variable step-size dual-mode blind equalization method for QAM signals, a storage medium and equipment, and belongs to the technical field of blind receiving and demodulation of wireless communication systems. The application solves the problem that the traditional hard switching mechanism is easy to cause system transient oscillation and lock loss. The application adjusts the iteration step size by constructing an error exponential function with a transient error signal as an independent variable, automatically gives the system a larger step size in the initial stage of the algorithm to accelerate convergence, and adaptively attenuates when the error tends to zero to suppress steady-state fluctuations, effectively overcoming the inherent contradiction between convergence speed and steady-state accuracy of the traditional fixed step-size algorithm; a soft switching mechanism based on a continuous confidence factor is used to replace the traditional hard switching decision, the global convergence ability of the MMA algorithm and the extremely high steady-state accuracy of the DD algorithm are smoothly and non-oscillatingly fused through a nonlinear fusion factor, transient oscillation and error propagation effect caused by mode switching are significantly suppressed, and system lock loss is avoided. The application can be applied to blind equalization of wireless communication systems.
