Z Zhu, AK Nandi - IEEE Transactions on Wireless …, 2014 - ieeexplore.ieee.org
In this paper, we propose a blind modulation classifier that differs from most existing classifiers. A low complexity minimum distance centroid estimator is suggested to estimate …
This paper addresses an adaptive implementation of frequency-domain channel estimators for orthogonal frequency-division multiplexing (OFDM) systems to reduce computational …
In estimation, the misspecified Cramer–Rao bound (MCRB), which is an extension of the well-known Cramer–Rao bound (CRB) when the underlying system model is misspecified …
Channel estimation is a challenging and timely issue for the 3rd Generation Partnership Project (3GPP) standardized low power wide-area network technology named narrowband …
Various methods are available for channel estimation in the orthogonal frequency division multiplexing and orthogonal frequency and code division multiplexing (OFCDM) based …
Single-tone and multi-tone transmissions in the narrowband Internet of Things (NB-IoT) uplink system can be accomplished by employing different orthogonal basis. In this paper …
Hilbert Huang transform (HHT) based data driven empirical mode decomposition (EMD) in conjunction with adaptive filter (AF) is proposed for estimation of communication channel in …
HR Park - IEEE Wireless Communications Letters, 2021 - ieeexplore.ieee.org
This letter addresses adaptive channel estimation for OFDM systems to reduce computational complexity. There are numerous methods suggested for low-complexity …
Present day wireless communication systems require a high data rate wireless access, for which the prerequisite is larger bandwidth. Obviously, to mitigate the inter symbol …
