Abstract: A self-adaptive waveform design method for unmanned aerial vehicle (UAV)-enabled integrated sensing and communication (ISAC) is provided. In a waveform designed by the self-adaptive waveform design method, subcarriers are classified into two types: modulation subcarriers and optimization subcarriers, to implement collaborative optimization of communication and sensing functions. In each transmission, symbols on the modulation subcarriers are generated through a maximum distance separable (MDS) code-based in-phase and quadrature modulation (MDS-IQM) method, whereas symbols on the optimization subcarriers are self-adaptively generated based on the symbols on the modulation subcarriers, to optimize communication performance, sensing performance, and a peak-to-average power ratio (PAPR) of the waveform. The self-adaptive waveform design method provides a feasible technical solution for a UAV-enabled ISAC application scenario.

Abstract: A lightweight intelligent localization method for multi-base-station integrated sensing and communications (ISAC) is provided. To improve stability and accuracy of a multi-base-station system in localizing an unmanned aerial vehicle (UAV), the present disclosure proposes a two-stage screening neural network architecture on a basis that a plurality of base stations estimate coordinates of the UAV by using a least squares subspace rotational invariance technique. This architecture uses a dynamic threshold grouping mechanism in a first stage to realize differentiable base station pre-screening through a straight-through estimator (STE); and in a second stage, designs a learnable exponential correction term that combines physical characteristics of a distance and a signal-to-noise ratio (SNR), and constructs a multi-objective loss function to simultaneously optimize localization accuracy and physical consistency.

Abstract: Post-copy is one of the two key techniques (besides pre-copy) for live migration of virtual machines in data centers. Post-copy provides deterministic total migration time and low downtime for write-intensive VMs. However, if post-copy migration fails for any reason, the migrating VM is lost because the VM's latest consistent state is split between the source and destination nodes during migration. PostCopyFT provides a new approach to recover a VM after a destination or network failure during post-copy live migration using an efficient reverse incremental checkpointing mechanism. PostCopyFT was implemented and evaluated in the KVM/QEMU platform. Experimental results show that the total migration time of post-copy remains unchanged while maintaining low failover time, downtime, and application performance overhead.

The control circuit is reliable and miniaturized with overcurrent protection and over temperature protection in an integrated circuit.
