Accurate Performance Analysis of Reconfigurable Intelligent Surfaces Over Rician Fading Channels

IEEE Wireless Communications Letters, 2021
We consider in this letter the performance of reconfigurable intelligent surface (RIS)-aided wireless networks over Rician fading channels. We derive new accurate closed-form approximations for several performance measures, including the outage ...

Double-factor Fading Memory Kalman Filter for Compensating Model Uncertainty

2021 40th Chinese Control Conference (CCC), 2021
In order to solve the divergence problem of Kalman filter caused by the model uncertainty in the dynamic system, this paper proposes an adaptive filter called double-factor fading memory Kalman filter. In fact, the recursive formulas of state estimations in Kalman filter can be derived by minimizing a quadratic cost function.

Secure Transmission in Cell-Free Massive MIMO With Low-Resolution DACs Over Rician Fading Channels

IEEE Transactions on Communications, 2022
This paper investigates the secure transmission in downlink cell-free massive multiple-input multiple-output (MIMO) systems in the presence of an active multi-antenna eavesdropper (Eve) over Rician fading channels, assuming that each access point (AP ...

RSS-Based Multiple Co-Channel Sources Localization With Unknown Shadow Fading and Transmitted Power

IEEE Transactions on Vehicular Technology, 2022
Multi-source localization based on received signal strength has drawn great interest in wireless sensor networks. However, the shadow fading term caused by obstacles cannot be separated from the received signal, which leads to severe error in location ...

Iterative receiver design in rayleigh fading using factor graph

The 57th IEEE Semiannual Vehicular Technology Conference, 2003. VTC 2003-Spring., 2004
In this paper we develop a novel approach for joint iterative channel estimation and LDPC decoding, based on the factor graph representation and sum-product algorithm. The fast flat fading channel is modeled as an AR process in order to characterize its temporal variation. By approximating the feedback message from the channel decoder as a Gaussian pdf,
