Due to the space limitation, communication receivers are extremely vulnerable to being blocked by high-power self-interference (SI) from the transmitter on the shared platform. The multipath amplitude and delay of the wireless channel are time-varying and frequency dispersion. As a result, the multitap self-interference cancellation (SIC) based on equal delay spacing is difficult to adapt to the dynamic changes of the SI channel over time and frequency, which leads to the degradation of SIC performance. The multitap SIC based on joint time-frequency domain channel measurement is proposed in the article. The multitap SIC model is established to analyze the demand for delay matching in the time-varying multipath channel. Under the joint constraints of the coherence time of the time-varying channel, the demand for interference cancellation ratio and delay resolution accuracy, the channel measurement method integrating time-domain correlation and frequency-domain sweep is designed to measure multipath delay. The prior information of the SI channel is provided to reconstruct the multitap SIC in real-time. Finally, the simulation and experiment results show that the proposed method in this article has high-precision delay measurement. The maximum error and standard deviation of the delay measurement are within 1ns and 0.5 ns. When the delay of the SI channel dynamically changes, compared with the equal delay spacing method, the SIC performance of the proposed method can be improved by more than 10 dB.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 4","pages":"1139-1151"},"PeriodicalIF":2.5,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144288197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 expression comes from converting the Fourier–Bessel transform describing the magnetic coupling between two generic turns belonging to the coils into a finite integral and then expanding the resulting integrand according to Gegenbauer addition theorem. This allows for term-by-term analytical integration, which expresses the inductance as an infinite sum of products of two modified Bessel functions, depending on the radii of the turns and the wavenumbers in the air space and the material medium. It is seen how the new developed formulation exhibits significantly better accuracy than previous well-established analytical approaches, the latter being subject to restrictive hypotheses, such as the magnetoquasistatic approximation. Moreover, in light of its superior performance in terms of computation time, the new solution offers a promising middle ground by combining the accuracy of numerical methods with the efficiency of analytical formulas.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 4","pages":"1360-1369"},"PeriodicalIF":2.5,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144278234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to the sensitivity analysis results of crosstalk parameters and the geometric characteristics of the cable bundle, dimensionality reduction is applied to the cable model. Subsequently, SROM is applied to perform uncertainty analysis on crosstalk for randomly sampled cable bundles, and the results are compared with a reference benchmark obtained via Monte Carlo method.

In this article, an automatic optimization method based on proximal policy optimization (PPO) reinforcement learning is proposed with the aim of suppressing FEXT through stub grid layout optimization. PPO is used to train the stochastic policy and it can effectively handle the action space. The stub grid layout is encoded into a matrix as the input of the algorithm, which iterates automatically using a reward mechanism. After optimization, the average FEXT between neighboring transmission lines can be suppressed from –28 to –41 dB. The experimental results demonstrate that the proposed method can effectively suppress FEXT and perform well under various pseudorandom binary sequence rates in the Gbps range.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 4","pages":"1370-1374"},"PeriodicalIF":2.5,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144228555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
