Power electronic converters (PEC) are integral to various sectors, including power systems, transportation, and industrial production, where their reliability significantly influences overall system performance. Despite its importance, current research has not thoroughly addressed the simultaneous impact of component performance degradation functional failures on This paper introduces a prediction method for PEC that considers both failure. Initially, digital prototype models developed...
This study investigates Kalman smoothing (KS)-based frequency-domain channel estimation for uplink multiple-input multiple-output (MIMO) orthogonal frequency division multiple access (OFDMA) systems with time-varying channels. The proposed KS scheme significantly outperforms the recursive least squares (RLS) in high signal-to-noise ratio (SNR) range, because of more effective exploitation signal information. In addition, interpolation is employed to improve accuracy by exploiting correlation...
This paper investigates carrier frequency offset (CFO) estimation and inphase/quadrature (I/Q) imbalance compensation in time-varying frequency-selective channels. We first propose a linear least squares (LLS) CFO approach which has lower complexity higher accuracy than the previous nonlinear methods. then Kalman filtering based I/Q presence of CFO, demonstrates good ability to track channel time variations with fast convergence speed, by nulling cyclic prefix (CP) including state vector...
Low-Earth orbit (LEO) satellites utilizing beam hopping (BH) technology offer extensive coverage, low latency, high bandwidth, and significant flexibility. However, the uneven geographical distribution temporal variability of ground traffic demands, combined with mobility LEO satellites, present challenges for efficient resource utilization. Traditional BH methods based on GEO fail to address issues such as satellite interference, overlapping mobility. This paper explores a Digital Twin...
In cognitive radio networks (CRNs) employing underlay multi-user scenarios, intelligent reflecting surface (IRS) plays a crucial function in augmenting total transmission rate for (CR) users, while adhering to restrictions caused by the interference from secondary users (SUs) primary (PUs). However, due passive characteristics of IRS, it operates non-cooperative relationship with both PU and SU network, resulting delayed information acquisition channel errors. Therefore, this research,...
