It is well known that the impulse response of a wideband wireless channel is approximately
sparse, in the sense that it has a small number of significant components relative to the …

In multiple-input multiple-output (MIMO) systems, it is crucial of utilizing the available
channel state information (CSI) at the transmitter for precoding to improve the performance …

Reconfigurable intelligent surface (RIS) can manipulate the wireless propagation
environment by smartly adjusting the amplitude/phase in a programmable panel, enjoying …

This paper considers and analyzes the performance of semiblind, training, and data-aided
channel estimation schemes for multiple-input multiple-output (MIMO) filter bank multicarrier …

The Jakarta Tool Suite (JTS) aims to reduce substantially the cost of generator development
by providing domain-independent tools for creating domain-specific languages and …

Hierarchical Bayesian Kalman filter (HBKF) based schemes are conceived for doubly-
selective sparse channel estimation in orthogonal space-time block coded (OSTBC) multiple …

Orthogonal frequency-division multiplexing (OFDM) combines the advantages of high
performance and relatively low implementation complexity. However, for reliable coherent …

Recommender systems are widely used for suggesting books, education materials, and
products to users by exploring their behaviors. In reality, users' preferences often change …

This paper improves the existing Kalman-based technique for detecting electromechanical
oscillations using Synchrophasor measurements. The novelty is the utilization of a …

This letter deals with the estimation of a flat fading Rayleigh channel with Jakes's spectrum.
The channel is approximated by a first-order autoregressive (AR (1)) model and tracked by a …
