Intuitively, the historical flight states of these agents reveal the intentions of their pilots, which directly influence their future trajectory. However, existing approaches struggle to handle the long-term dependencies present in flight states and overlook the fundamental connection between an agent's behavioral intention and its trajectory. To address these challenges, this paper proposes a hybrid cached attention encoder-decoder (CAED) framework for aircraft trajectory prediction, with behavioral intention recognition as an auxiliary task. Specifically, CAED incorporates a dynamic cache within the encoder-decoder structure to capture the long-term dependencies between the targets' historical and current flight state representations. During the training process, an additive selection mechanism is proposed to select relevant history states stored in each memory slot that contribute most to the prediction of future trajectories. Finally, we design a scoring function and implement multi-task learning to jointly train our model. The extensive experiments on two aircraft trajectory prediction datasets clearly validate the superiority of our proposed CAED compared with various existing baselines.","PeriodicalId":50701,"journal":{"name":"Chinese Journal of Electronics","volume":"35 3","pages":"1139-1152"},"PeriodicalIF":4.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11595445","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148507943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While single error correction-double error detection-double adjacent error correction (SEC-DED-DAEC) codes are effective against adjacent double-bit errors, a critical challenge remains: many existing implementations are prone to miscorrecting certain non-adjacent double-bit errors, creating a reliability vulnerability. Furthermore, current solutions often suffer from poor scalability or significant hardware overhead. This paper addresses these challenges by proposing a novel SEC-DED-DAEC algorithm that guarantees a zero error rate for all double-bit errors. The proposed algorithm is highly scalable, capable of generating optimized check matrices for data widths ranging from 8 to 512 bits. Through a systematic construction and optimization process, our approach not only eliminates miscorrection but also reduces redundancy. Compared to state-of-the-art zero-errorrate SEC-DED-DAEC schemes, our method requires fewer check bits, demonstrates superior scalability, and as verified by hardware synthesis, results in lower area, latency, and power consumption in its encoder and decoder circuits.","PeriodicalId":50701,"journal":{"name":"Chinese Journal of Electronics","volume":"35 2","pages":"866-876"},"PeriodicalIF":3.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11554551","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148196150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, it has emerged as a novel approach for addressing large-scale and intricate tasks. However, the collected sensing data often contain valuable information, necessitating careful consideration of data privacy. Traditional data privacy protection schemes are predominantly centralized, which makes them susceptible to single-point failures, trust crises, and scalability issues. Meanwhile, these traditional schemes fail to account for the risk of key leakage resulting from side-channel attacks within real network environments. Therefore, a distributed and leakage-resilient privacy protection mechanism has great practical value in crowd-sourcing applications. To this end, we propose a blockchain-based secure data sharing mechanism for crowdsourcing applications. Our main contribution is to propose an identity-based encryption scheme that achieves continuous leakage-resilient security. From the adversary's perspective, the ciphertext structure in the scheme seems completely random, making it infeasible to extract private key information. We establish the proposed scheme's chosen-ciphertext attack security under the selective-ID model, relying on the decisional weaker bilinear Diffie-Hellman inversion assumption. Theoretical analysis validates the scheme's advantages, feasibility, and effectiveness.","PeriodicalId":50701,"journal":{"name":"Chinese Journal of Electronics","volume":"35 3","pages":"1256-1268"},"PeriodicalIF":4.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11595437","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148443339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these limitations, we propose ternary logic synthesis system (Tlsys), the first synthesis framework that synthesizes ternary register-transfer-level (RTL) designs into gate-level netlists. By proposing a ternary Verilog description guidelines, Tlsys enables the RTL design of large-scale ternary circuits. Furthermore, translation and mapping methodologies are proposed to transform ternary RTL into an equivalent carbon nanotube field-effect transistors (CNFET)-based gate-level netlist. In addition, a verification methodology for ternary netlists is proposed. Compared with other ternary logic synthesis tools, Tlsys demonstrates a capability in handling large-scale circuit designs.

However, traditional ground-centric handover architectures struggle with excessive signaling overhead and latency as networks scale to accommodate emerging services (e.g., remote control, broadband civil aviation, personal broadband). To address these differentiated services, we propose a space-ground distributed inter-satellite handover control architecture (SGDISHCA) that migrates radio resource control (RRC) and authentication management function (AMF) to satellites, establishing a distributed control paradigm. Specifically, we analyze the influence of the minimum elevation angle between the ground location area and the satellite on the delay and handover times, and establish the satellite-location area correlation model. According to the model, we design an on-demand allocation algorithm that dynamically aligns channel allocation rates with heterogeneous service demand rates, jointly optimizing QoS guarantees and resource efficiency. Through the analysis of simulation results, we validate that our proposed scheme reduces handover delays and signaling overhead. Furthermore, our scheme exhibits a remarkable enhancement in user satisfaction and optimization of system resource utilization. We also investigate the effect of ground station distribution on network performance and find that the network performance exhibits marked improvements with fewer and denser ground stations, facilitated by the on-demand allocation algorithm.","PeriodicalId":50701,"journal":{"name":"Chinese Journal of Electronics","volume":"35 3","pages":"1058-1072"},"PeriodicalIF":4.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11595291","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148506683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared to conventional cantilever beam structures, this folded design achieves significant volume reduction. The semi-circular cantilever configuration also enables superior multi-directional energy harvesting and allows for frequency response tuning by adjusting the angle of the auxiliary beams and the size of the proof mass. Four FSC-PEH variants with different auxiliary beam angles were designed and experimentally measured. The configuration with a 0° auxiliary beam angle (designated PEH-A) demonstrated the best performance. Under a 0.1g acceleration, PEH-A exhibited two distinct resonance peaks at 76 Hz and 106 Hz. The corresponding open-circuit voltages reached 14.60 V and 18.64 V, respectively. The normalized power density (NPD) for the first mode is 15.3 <tex>$mu mathrm{W}cdot mathrm{g}^{-2}cdot text{mm}^{-3}$</tex>. When the base excitation is offset by 45°, the voltage at the first-order resonant frequency drops to 8.98 V (approximately 61.5% of the peak value), and the voltage at the second-order resonant frequency drops to 13.95 V (approximately 74.8% of the peak value). This vividly demonstrates its ability to collect energy in multiple directions. After integrating an adaptive power management module, the system is able to stably output a 3.3 V direct current voltage under 0.1g vibration. This output successfully powered a low-power temperature and humidity sensor (AHT10), enabling its normal operation. Therefore, this piezoelectric energy harvesting system shows promise for effectively powering low-power chips and sensors in applications such as rail transit and the Internet of things.","PeriodicalId":50701,"journal":{"name":"Chinese Journal of Electronics","volume":"35 3","pages":"935-945"},"PeriodicalIF":4.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11595293","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148506686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerical simulations show that the proposed method maintains low S-parameter reconstruction errors in the 10 MHz-20 MHz frequency range, with magnitude MSE values at the 10<sup>−6</sup> level. Experimental validation using a near-field measurement system further shows that more than 89% of the scanned regions have relative errors below 0.20%, with a maximum average error of 0.57%.
