Large-scale orthogonal frequency division multiplexing (OFDM) multiple-input multiple-
output (MIMO) is a promising candidate to achieve the spectral efficiency up to several tens …

A cooperative communication system explores a new dimension of diversity in wireless
communications to combat the unfriendly wireless environment. While this emerging …

Due to the fact that the quality of the received signal is adversely affected by the beam squint
phenomenon, which is especially pertinent to the millimeter wave (mmwave) bands, many …

There has been increasing demand for accessible radio spectrum with the rapid
development of mobile wireless devices and applications. For example, a GHz of spectrum …

In this paper, the Gaussian quasi-maximum likelihood estimator (GQMLE) is generalized by
applying a transform to the probability distribution of the data. The proposed estimator …

As the key technology of Chinese national digital television terrestrial broadcasting (DTTB)
standard, time domain synchronous OFDM (TDS-OFDM) has high spectral efficiency at the …

This paper considers the situation where users that experience high-mobility transmit data
over frequency-selective channels, resulting in a doubly selective channel model (ie, time …

This article presents an iterative minimum mean square error-(MMSE-) based method for the
joint estimation of signal-to-noise ratio (SNR) and frequency-selective channel in an …

In this correspondence, we propose an iterative “turbo” channel estimation algorithm for
known symbol padding (KSP) orthogonal frequency-division multiplexing (OFDM), where …
