Recently, several approaches have been proposed for the equalization of orthogonal
frequency-division multiplexing (OFDM) signals in challenging high-mobility scenarios …

We find that placing each pilot tone in an equally spaced manner according to the
conventional placement scheme is not suitable for doubly selective channel estimation. In …

Adaptive techniques play a key role in modern wireless communication systems. e concept
of adaptation is emphasized in the Adaptation in Wireless Communications Series across all …

In this paper, we derive an analytical expression for the bit error rate (BER) of binary phase
shift keying (BPSK) symbols transmitted over a multiple-input multiple-output (MIMO) system …

We propose channel estimation and direct equalization techniques for transmission over
doubly selective channels. The doubly selective channel is approximated using the basis …

Recovering data symbols in a wireless communications system consists of two main
estimation steps: channel estimation based on transmitted pilot symbols, and estimation of …

This paper investigates the capacity of radio channels when iterative channel estimation,
data detection, and decoding are employed. Knowing the capacity gain from iterative …

We propose in this work to employ the Box-LASSO, a variation of the popular LASSO
method, as a low-complexity decoder in a massive multiple-input multiple-output (MIMO) …

In this paper, we consider noncoherent single-antenna communication over doubly selective
block-fading channels with discrete block-fading interval N. In our noncoherent setup …

This paper considers the problem of symbol detection in massive multiple-input multiple-
output (MIMO) wireless communication systems. We consider hard-thresholding preceeded …
