We consider the task generated by device comprises multiple dependent subtasks, whose relationship can be represented by directed acyclic graph. These subtasks can be cooperatively executed by device and edge server, via proper task scheduling based on their dependencies. The energy required for local processing and offloading is harvested from the energy transmitter through wireless power transfer (WPT). We formulate an optimization problem that jointly determines the WPT duration and subtask scheduling to minimize the overall task completion time. The formulated problem is a mixed-integer nonlinear programming problem, with mutually coupled optimization variables. To resolve it with low complexity, we adopt the deep reinforcement learning approach to design a deep Q-network (DQN) based algorithm. To facilitate the learning process of proposed algorithm, we further introduce a novel mechanism to incorporate the derived time-equivalent cost of WPT duration into the reward function. Consequently, the decision on WPT duration can be decoupled and replaced during the learning process, allowing the DQN agent to focus solely on the optimal offloading decisions. Simulation results reveal that the proposed algorithm achieves near-optimal performance, significantly outperforming other benchmark algorithms.","PeriodicalId":50701,"journal":{"name":"Chinese Journal of Electronics","volume":"35 5","pages":"1929-1940"},"PeriodicalIF":4.5,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149188731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The collaborative term of MEC as multi-access edge computing supports the intelligent utilization of network, computing, and storage resources for efficient resource management and service availability. However, ensuring service availability in a tactile internet environment is still challenging, while parallel and dynamic resource utilization becomes the key issue. Virtual resource management and the slicing approach can provide dynamically classified scenarios by arranging network entities and resources into multiple logically independent networks. Hence, the independent virtual functions through MEC-based access network slicing can improve existing MEC approaches for tactile internet services. This manuscript proposes research on centralized virtual slicing to efficiently handle distributed MEC resources, including computing, networking, and storage. Besides, these resources can be efficiently utilized in the proposed MEC slicing approach, avoiding over-provisioning of available MEC resources. Whereas over-provision of resources greatly impacts the high bandwidth and ultra-low latency requirements of tactile services. A sliced MEC (SL-MEC) framework is proposed, considering the resource coupling throughout the similarity matrix. With respect to tactile internet, the SL-MEC generates the aggregated slices 6× faster than the benchmark algorithms, with guaranteed resource availability.","PeriodicalId":50701,"journal":{"name":"Chinese Journal of Electronics","volume":"35 5","pages":"2074-2084"},"PeriodicalIF":4.5,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149188752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the proposed algorithm, a three-dimensional state space integrating error, integral error, and previous error is constructed, forming the basis for the algorithm's state perception. Subsequently, equidistant binning is used to discretize the state space, and PID controller parameters are adaptively tuned through incremental actions from a finite adjustment set. Next, a multi-objective dynamic reward function that combines error suppression, control smoothness, and parameter stability is proposed. Furthermore, the AMOR-QL algorithm is developed by employing an event-triggered experience storage mechanism combined with an attention-based experience replay strategy, in which state similarity analysis guides the learning process towards context-relevant experiences. This design enables the optimal PID controller parameters to be learned using only data with guaranteed stability, while significantly improving learning efficiency.

By analyzing the electromagnetic emissions, eavesdroppers can reconstruction sensitive data, making it a critical threat to information security. Traditional information leakage detection technologies typically employ signal isolation techniques to separate red and black signals from emission signals, reducing the red signal below a safe threshold. However, these methods fail to quantitatively assess the overall security of ITE and rely on the level and subjective judgment of the testing technician. To address this issue, we propose a mathematical model for active electromagnetic information leakage from the perspective of information theory. This model uses the minimum amount of information accessible to eavesdroppers as a threshold to assess the risk of electromagnetic information leakage. To validate the proposed quantitative model, we designed an experimental setup to monitor emission signals from a video graphics array interface using a current probe. The electromagnetic information leakage was subsequently evaluated through both theoretical modeling and practical image reconstruction using a custom-developed algorithm. Experimental results confirm the model's validity while demonstrating its advantages over conventional approaches that depend on inspectors' subjective assessments.","PeriodicalId":50701,"journal":{"name":"Chinese Journal of Electronics","volume":"35 5","pages":"2048-2057"},"PeriodicalIF":4.5,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149188661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it encounters two key challenges: high communication cost of federation aggregation due to frequent updates of model parameters in Internet of vehicles; and low model aggregation accuracy due to the non-adaptive gradient quantization strategy. To this end, we propose Hermes, which first calculates the gradient variance of vehicle nodes to dynamically adjust the quantization level, and then utilizes the scalar of the quantization level to alleviate the ineffective quantization phenomenon of gradient quantization to zero, followed by employing an error feedback mechanism to guarantee the integrity of the model. Experimental results show that, compared to the other baselines, Hermes reduces upload traffic to approximately 2.94% of the full-precision transmission volume; meanwhile, the average accuracy of the aggregate model is improved by 2.49%.

Existing massive digital AirComp (MD-AirComp) schemes have shown promising performance in federated edge learning and are compatible with current digital wireless networks. Nevertheless, these schemes depend on channel pre-equalization, which may amplify computation errors in the presence of channel estimation inaccuracies, thereby limiting its practical use. In this paper, we propose a blind MD-AirComp+ scheme, which takes advantage of the channel hardening effect in massive multiple-input multiple-output systems. We provide an upper bound on the computation mean square error, analyze the tradeoff between computation accuracy and communication overhead, and determine the optimal quantization level. Additionally, we introduce a deep unfolding algorithm to reduce the computational complexity of solving the underdetermined detection problem formulated as a least absolute shrinkage and selection operator optimization problem.

Through the implementation of tight coupling techniques between patch elements and the strategic integration of monopole-like metal walls, the antenna's impedance bandwidth and beamwidth have been significantly augmented. To elucidate the beam broadening mechanism, a comprehensive analysis of the proposed antenna has been conducted utilizing the equivalence principle. Simulation and measurement results demonstrate that the proposed antenna achieves a bandwidth exceeding 5 GHz, encompassing the 76 GHz–81 GHz automotive radar band.

The architecture comprises a parallel-to-serial converter (P2S), a clocking module, and a driver, supporting 1 Gbps to 32 Gbps data rates. To enhance single-event effects (SEEs) tolerance, a foreground duty-cycle correction technique is implemented, along with SEE-hardened flip-flops and latches based on the dual inter-locked cell topology. The TX is fabricated in a sub-20 nm fin field-effect transistor (FinFET) technology. At 32 Gbps, the TX achieves an output eye height of 110 mV and an eye width of 18.5 ps (0.59 UI), with a total power consumption of 115.8 mW. SEE sensitivities have been characterized by heavy ions with a linear energy transfer from 5.5 MeV·cm2/mg to 77.1 MeV·cm2/mg, with only bit-error single-event transients (BSETs) and non-error fake single-event transients (FSETs) observed. Pulsed laser tests with energy up to 1.0 nJ were conducted, and the P2S was identified as the most SEE-sensitive module, with a saturation cross-section of approximately 3 × 10−6 cm2 at 0.8 nJ.
