Efficient time domain threshold for sparse channel estimation in OFDM system

First a coarse esti- mation is done in order to provide the time reference for symbol synchronization and then, working in the frequency domain, a high resolution estimation of

As the deterministic bounds, the Bayes- ian Cram´er-Rao bound and the Bayesian Bhattacharyya bound are small error bounds contrary to the Bobrovsky-Zaka¨ı bound and the

For each model, we propose to characterize the threshold region using some deterministic lower bounds on the estimator’s mean square error (i.e., lower bounds w.r.t.

An expression of the minimum mean square error (MMSE) of the linear MMSE channel estimation is given in the case of a non-inverti- ble channel covariance matrix, as in

In this paper, we investigate the effective exponential signal to interference and noise ratio method (EESM) in the MIMO-OFDM systems to predict the BER at the output of

(6) As a conclusion, it can be observed that, for an angular speed with small variations, the Elapsed Time technique creates a low-pass filter with a sinc π shape based on ∆θ
