It is significant to fit a Gaussian function with the observation data for artificial intelligence or
other engineering fields. Considering the influence of noises, this article proposes a …

A new approach of channel estimation for multiantenna systems is put forward in this paper,
which can be adopted in high-mobility situations such as high speed trains. The channel …

Robust spring energy state identification of the operating mechanism is of great significance
for monitoring the overall performance of the circuit breakers. However, rapid monitoring of …

Orthogonal frequency division multiplexing (OFDM) systems have inherent symmetric
properties, such as coding and decoding, constellation mapping and demapping, inverse …

Structured estimation of channel impulse response (CIR) is considered in orthogonal
frequency division multiplexing (OFDM) systems for which the channel exhibits a sparse …

Wireless broadband transmission channels usually have time-domain-sparse properties,
and the reconstruction of these channels using a greedy search-based orthogonal matching …

Wireless communication channels are highly prone to interference in addition to the
presence of additive white Gaussian noise (AWGN). Stochastic gradient (SG)-based non …

In high-speed digital wireless communication applications, the intersymbol interference
channel may have spectral nulls or erasures, which may degrade the orthogonal frequency …

Wireless communication link at the physical layer can be described as a signal transmission
over multiple propagation paths which are different in the gain and the delay. But in reality …

The paper presents the problem of determining the impulse response of a sparse channel,
in which the propagation path delays are not restricted to the sampling grid of the signal …
