Time-varying narrowband Multiple-Input Multiple- Output Orthogonal Frequency Division Multiplexing (MIMO OFDM) channel estimation is considered. The effect of finite bandwidth and practical pulse shapes renders the sparse MIMO-OFDM channel, non-spars

The Bayesian inference is leveraged for target tracking from radio signals collected from access points (APs). The density of the moving object as well as its distance from the transmitted wireless signal substantially affect the signal strength arri

In this paper, the estimation of a narrowband time-varying channel under the practical assumptions of finite block length and finite transmission bandwidth is investigated. It is shown that the signal, after passing through a time-varying narrowband

In this paper, the CramA©r Rao bound (CRB) on the time-varying narrowband leaked Multiple-Input Multiple- Output Orthogonal Frequency Division Multiplexing (MIMO OFDM) channel estimators is derived, under the assumption of deterministic sequences. T

In this paper, the incorporation of algebraic varieties is considered for structured estimation of nonlinear trajectories. The background subtraction model is extended beyond sparse and low-rank decompositions. The algebraic varieties model is introd

In this paper, target tracking constrained to short-term linear trajectories is explored. The problem is viewed as an extension of the matrix decomposition problem into low-rank and sparse components by incorporating an additional line constraint. Th

In this paper, the problem of time-varying narrowband leaked Orthogonal Frequency Division multiplexing (OFDM) channel estimation is considered. The leakage effect results from practical constraints on communication systems: finite bandwidth and bloc

In this paper, the incorporation of a line constraint is considered for structured estimation. In particular, multiple forms of structure on matrices are extended from low-rank and sparsity. The line constraint is introduced via a rotation that yield
