However, security threats, notably the interception of sensitive data, remain a significant challenge for secure communications. To safeguard the confidentiality of transmitted semantics and effectively counteract eavesdropping threats, this letter proposes a secure deep learning-based semantic communication system, SecureDSC. It comprises semantic encoder/decoder, channel encoder/decoder, and encryption/decryption modules with a key processing network. By incorporating a symmetric encryption module and an attacker-oriented adversarial network, SecureDSC guarantees the secure transmission between legitimate users in the semantic communications. Besides, experiments are conducted to evaluate the effectiveness and feasibility of the proposed scheme.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"29 3","pages":"487-491"},"PeriodicalIF":3.7,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594387","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}

In this letter, we propose a novel low-complexity distributed WMMSE (LCD-WMMSE) algorithm, which is implemented over a decentralized architecture based on ring topology. Although each distributed unit (DU) in LCD-WMMSE works only with the local channel state information (CSI), LCD-WMMSE algorithm is still able to approach the performance of traditional WMMSE. Moreover, we show that LCD-WMMSE is also scalable since its required interconnection bandwidth is independent of the number of transmitter antennas, making it promising to various scenarios of massive MIMO. Simulation results validate that the proposed LCD-WMMSE algorithm not only achieves the low complexity cost in a distributed manner but also exhibits negligible performance loss.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"29 3","pages":"482-486"},"PeriodicalIF":3.7,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594379","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}

In RIS-DM-DCSK, a dual M-ary DCSK signal is designed to transmit twice the number of modulated bits compared to a standard M-ary DCSK signal while permutation index modulation is employed to convey additional index bits, thereby enhancing energy efficiency. Furthermore, we propose a permutation index detection and dual M-ary DCSK demodulation algorithm to recover the transmitted bits. The bit error probability (BEP) of RIS-DM-DCSK is analyzed over a Rayleigh fading channel.

Considering the mean-squared error (MSE) for estimation performance metric, the Bayesian Cramér-Rao lower bound (BCRB) is widely used in literature as a proxy of the MSE; however, the BCRB is not generally tight even asymptotically except for restrictive distributions. Instead, we characterize the full tradeoff between information rate and the exact MSE using the asymptotically tight BCRB (ATBCRB) analysis, a recent variant of the BCRB. Our characterization is applicable for general channels as long as the regularity conditions are met, and the proof relies on constant composition codes and ATBCRB analysis with the codes. We also perform a numerical evaluation of the tradeoff in a variance estimation example, which commonly arises in spectrum sensing scenarios.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"29 3","pages":"477-481"},"PeriodicalIF":3.7,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594376","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}

In particular, we consider the multiuser multiple-input and single-output (MISO) system under the presence of a multi-antenna eavesdropper, where full-duplex (FD) legitimate users proactively emit artificial noise (AN) to disrupt the eavesdropper’s reception. Towards this end, we formulate the secrecy energy efficiency (SEE) maximization problem and propose an alternating optimization-based two-level algorithm to solve it, where the semi-definite programming (SDP) combined with successive convex approximation (SCA) is adopted.

We study the fundamental capacity region where rather surprisingly, we show that a dynamic antenna position plan, which at some point within the communication block rotates the transmit beams to cover both the desired and the unintended receivers, may enhance attainable rates and maximize network capacity. We provide theoretical bounds that define the limits of attainable reliable rates taking into account the non-stationary nature of channels with controllable statistics and the fact that the transmitters are distributed. We also present a linear opportunistic communication protocol that exploits the non-causal knowledge of statistical changes to improve network capacity. We compare the results against various benchmarks and prove the superiority of the proposed protocol.

To improve the design flexibility, the sensing beam pattern is distributed among different subcarriers for optimization, with phase vectors introduced to transform the modulus summation into a linear summation. Additionally, by decoupling the multi-variable constraint, we employ the alternating direction method of multipliers to decompose the original problem into manageable subproblems, which are iteratively optimized.

This letter investigates the potential of a quantum-centric optimisation approach for service placement in 6G MEC. Specifically, we formulate a mixed-integer binary programming problem that aims to minimise both service costs and delay by optimising service placement decisions, subject to constraints on service availability and the computing budget of edge servers. The formulated problem is NP-hard, making it computationally challenging for classical methods to solve. To address this, we develop a quantum-centric optimisation solution that efficiently finds optimal binary solutions for the problem, demonstrating potential for tackling medium-to-large-scale instances.
