To solve the complex and non-convex fractional programming problem of SEE maximization, we design an efficient method based on the Dinkelbach algorithm and alternative optimization, which divides the solving process into an outer algorithm and an inner algorithm. For the outer algorithm, we introduce the Dinkelbach operator to transform the fractional programming problem into a tractable subtractive form, involving the beamforming (BF) vector, AN vector, and IRS reflecting phase shift. In the inner algorithm, the integer problem is decomposed into two simpler sub-problems, then sub-optimal solutions can be obtained by iteratively optimizing the sub-problems. The simulation results verify that using AN can efficiently enhance the SEE in IRS-aided MISO systems, and the advantage of incorporating AN becomes even more pronounced in the presence of multiple eavesdroppers.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"29 4","pages":"858-862"},"PeriodicalIF":3.7,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143817883","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}

However, the relay’s energy supply is a common constraint factor of relay-assisted AirComp networks. To address the power constrained issue, we introduce power-splitting (PS) relays into an AirComp network, where the relays can harvest energy from the transmitted signals of the sensors and the FC by the PS scheme and then forward the signals to the FC by using the harvested energy. Our objective is to minimize the computational mean square error (CMSE) at the FC by jointly optimizing the transmit coefficients at the sensors, the amplify and forward (AF) coefficients and PS ratios at the relays, and the de-noising factor at the FC, under the individual power constraints at the sensors and relays. The optimization problem is highly non-convex and difficult to solve. By exploiting the inexact block coordinate descent (IBCD) algorithm and the constrained concave-convex procedure (CCCP), we propose an IBCD-CCCP algorithm to solve the optimization problem effectively. Numerical results are presented to demonstrate the effectiveness of our scheme as compared to the baseline methods.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"29 4","pages":"853-857"},"PeriodicalIF":3.7,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143817916","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}

However, existing multi-stage codebook design methods limit the potential coding gain. Besides, although the minimum Euclidean distance (MED) is commonly used as the performance criterion for additive white Gaussian noise (AWGN) channels, existing works indicate that the MED does not always reflect the actual error performance. This letter proposes a novel structured codebook design for joint parameter optimization based on the union bound, which addresses the mismatch of MED and enhances the error performance. Specifically, we develop strategies for constructing the one-dimensional constellations, CMMs, bit labeling set, and treat these factors as optimizable parameters. The union bound is employed as the design metric to jointly optimize the aforementioned parameters with genetic algorithm (GA). Simulation results demonstrate the superiority of the proposed codebook design method.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"29 5","pages":"913-917"},"PeriodicalIF":3.7,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143929860","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 most significant and notable difference between the two is the optical power, which is several orders (7 or more) of magnitude distinct from each other. There are several approaches to address this issue – in this letter, at a glance, the realistic and practical approach, which relies on the selection of high-grade optical filters, was chosen. Rigorous, however affordable, optical filtering is required to avoid any possible crosstalk, not only from the classical data signals but also from the spontaneous nonlinear Raman scattering effect. In our experimental verification, it has been demonstrated that the selection of high-grade transmission components is a crucial element in the success of multiplexing strong and weak optical signals in a single fiber. In real-world applications, this approach significantly reduces infrastructure costs by eliminating the need for additional fiber.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"29 5","pages":"908-912"},"PeriodicalIF":3.7,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10902004","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143929859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}
