Nowadays, a large amount of information has to be transmitted or processed. This implies
high-power processing, large memory density, and increased energy consumption. In …

Single-pixel imaging (SPI) uses a single-pixel detector instead of a detector array with a lot
of pixels in traditional imaging techniques to realize two-dimensional or even multi …

The space-air-ground integrated network (SAGIN) aims to provide seamless wide-area
connections, high throughput and strong resilience for 5G and beyond communications …

Accurate channel tracking with a small pilot overhead is vital for real-time massive multiple-
input and multiple-output (MIMO) communication over a dynamic channel. Recently …

This study focuses on channel estimation for reconfigurable intelligent surface (RIS)-
assisted mmWave systems, in which the RIS is used to facilitate base-to-user data transfer …

The pilot overhead provides fundamental limits on the performance of massive multiple-
input multiple-output (MIMO) systems. This is because the performance of such systems is …

Recently, massive multiple input multiple output (MIMO) channel tracking in the fifth
generation (5G) new radio (NR) systems has attracted intensive interest. By exploiting the …

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

In this paper, we address the problem of online (sequential) recovery of temporally
correlated sparse vectors sharing a common support, from noisy underdetermined linear …

The space-air-ground integrated network (SAGIN) has drawn increasing attention for its
benefits, such as wide coverage, high throughput for 5G and 6G communications. As one of …
