Performance Analysis of RIS-Assisted Large-Scale Wireless Networks Using Stochastic Geometry

no code implementations18 Aug 2022 Tianxiong Wang, Gaojie Chen, Mihai-Alin Badiu, Justin P. Coon

Furthermore, it is also unveiled that the system performance is independent of the density of TXs with the nearest association strategy in the interference-limited scenario.

Study of Intelligent Reflective Surface Assisted Communications with One-bit Phase Adjustments

no code implementations22 Aug 2020 Tianxiong Wang, Gaojie Chen, Justin P. Coon, Mihai-Alin Badiu

For the imperfect phase configuration, we assume that each element of the IRS has a one-bit phase shifter (0{\deg}, 180{\deg}) and an expression for the outage probability is obtained in the form of an integral.

no code implementations14 Aug 2020 Zijie Ji, Phee Lep Yeoh, Deyou Zhang, Gaojie Chen, Yan Zhang, Zunwen He, Hao Yin, Yonghui Li

We propose and analyze secret key generation using intelligent reflecting surface (IRS) assisted wireless communication networks.

Chernoff Bounds and Saddlepoint Approximations for the Outage Probability in Intelligent Reflecting Surface Assisted Communication Systems

no code implementations12 Aug 2020 Tianxiong Wang, Gaojie Chen, Justin P. Coon, Mihai-Alin Badiu

Furthermore, through an exact asymptotic (a large number of reflecting elements) analysis based on a saddlepoint approximation, we derive closed-form expressions of the outage probability for systems with and without a direct link and obtain the corresponding diversity orders.
