In the network, the strong user wiretaps the signals of the weak user while an external warden monitors the communication behaviors of the strong user. To address the issue, a random artificial noise (AN) based beamforming is adopted, which not only reduces the eavesdropping rate of the strong user but also confuses the warden. We consider the worst case, where the warden can minimize the detection error probability (DEP) by optimizing its detection threshold. Further, we characterize the closed-form expressions of the average minimum DEP of the warden, the connection outage probabilities of the NOMA users and the secrecy outage probability of the weak user under the imperfect successive interference cancellation (SIC). To improve the performance, an effective covert rate maximization problem is formulated, under the constraints of the covertness, reliability and secrecy, which is analytically solved. Numerical results validate the superiority of the proposed scheme.","PeriodicalId":13343,"journal":{"name":"IEEE Wireless Communications Letters","volume":"12 12","pages":"2178-2182"},"PeriodicalIF":6.3,"publicationDate":"2023-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62415086","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, the problem of the joint channel estimation and device activity detection is investigated in an RIS empowered massive Internet of Things system. To achieve a satisfactory trade off between the system performance and the hardware overhead, the mixed analog-to-digital converters (ADCs) are configured in the network. Due to the large number of antennas equipped at the base station, the channel estimation and activity detection can be performed from the perspective of multiple measurement vector. Furthermore, the nonlinear theoretical analysis of the channel estimation and the activity detection is provided based on the Bayesian theory. Numerical results verify the effectiveness of the proposed nonlinear channel estimation and active device detection in terms of error probability and computational complexity.","PeriodicalId":13343,"journal":{"name":"IEEE Wireless Communications Letters","volume":"12 11","pages":"1976-1980"},"PeriodicalIF":6.3,"publicationDate":"2023-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62415043","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, how to optimize these amplification factors is still an open issue. In this letter, we propose an energy-efficient design for AAJ-enabled communications systems. In particular, the energy efficiency problem is studied and formulated as the total energy consumption minimization subject to the minimum required rate and the hardware limit of the power amplifier, which turns out to be a quadratic programming problem. The corresponding optimal amplification factors are obtained by the interior point method. Numerical results indicate that with the equal transmission rate, the proposed energy-efficient AAJ scheme can provide 76.8% energy saving as compared with the direct transmission.","PeriodicalId":13343,"journal":{"name":"IEEE Wireless Communications Letters","volume":"12 12","pages":"2173-2177"},"PeriodicalIF":6.3,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62414899","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}

Also, the localization of user equipment (UE) becomes more challenging in multipath environments. In this letter, we propose a localization algorithm for a UE in the near-field of a RIS in multipath environments. The proposed scheme utilizes a light detection and ranging (LiDAR) to assist the UE positioning by providing geometric information about some of the scatterers in the environment. This information is fed to a sparse recovery algorithm to improve the localization accuracy of the UE by reducing the number of variables (i.e., angle of arrivals and distances) to be estimated. The numerical results show that the proposed scheme can improve the localization accuracy by 65% compared to the standard compressed sensing (CS) scheme.","PeriodicalId":13343,"journal":{"name":"IEEE Wireless Communications Letters","volume":"12 12","pages":"2168-2172"},"PeriodicalIF":6.3,"publicationDate":"2023-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62414816","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}

Considering user fairness, we maximize the minimum secrecy rate (MSR) among all legitimate users subject to the quality of service (QoS) constraints and transmit power constraint. A feasibility check problem is first presented to avoid infeasible cases. Then, a successive convex approximation-based algorithm is proposed to iteratively optimize the beamforming design. Numerical results show that the proposed RSMA-based design outperforms the baseline design in terms of MSR within certain QoS requirement ranges to trade security for reliability by balancing the power allocated to the common stream and private streams. And the performance advantage enlarges as the number of collusive eavesdroppers increases.","PeriodicalId":13343,"journal":{"name":"IEEE Wireless Communications Letters","volume":"12 1","pages":"1504-1507"},"PeriodicalIF":6.3,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62414388","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 investigate the simultaneous lightwave information and power transfer (SLIPT) technique deployed for the visible light communication (VLC) system, and implement SLIPT by adjusting the association between optical IRS (OIRS) and transceivers to maximize the harvested energy while guaranteeing the achievable data rate. Further, a binary assignment matrix is introduced to represent the association behavior mentioned above, and then the problem is solved by relaxing the constraints of the assignment matrix. Moreover, an iterative optimization algorithm and a greedy strategy are also proposed to solve the non-convex problem.

The HTM considers the receiver’s direct link signal decoding capability and the tag circuit’s sensitivity. It utilizes opportunistic successive interference cancellation (SIC) and ensures continuous reflection while minimizing active power consumption. The tag adaptively reflects a portion of the radio frequency (RF) source signal via passive transmission (PT), except when insufficient harvested energy requires the tag to rely on battery power, reflecting the entire RF source signal. Tight closed-form approximations for outage probabilities, derived using Gaussian-Chebyshev quadrature, are presented. The outage performance of traditional PT, operating with fixed and variable reflection coefficients, is also analyzed for comparison. Simulation results confirm the accuracy and precision of the derivations and demonstrate the superior performance of the proposed HTM compared to traditional PT.","PeriodicalId":13343,"journal":{"name":"IEEE Wireless Communications Letters","volume":"12 12","pages":"2163-2167"},"PeriodicalIF":6.3,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62414799","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}
