智能超表面具有智能化改变无线环境的能力. 考虑到宽带系统中子信道的衰减和拥挤的用户,
我们将智能超表面引入具有正交频分复用(orthogonal frequency division multiplexing, OFDM) …

This paper focuses on addressing the challenge of estimating multiple-input multiple-output
(MIMO) channels for wireless communication between a ground base-station and a moving …

This paper investigates a physical layer key generation (PLKG) scheme for reconfigurable
intelligent surface (RIS)-aided millimeter-wave (mmWave) multiple-input multipleoutput …

The beam squint effect, which manifests in different steering matrices in different sub-bands,
has been widely considered a challenge in millimeter wave (mmWave) multiinput multi …

In cell-free (CF) networks, access points (APs) jointly serve the user equipments (UEs). In
user-centric (UC) variant, only a handful of APs serve a particular UE, namely the ones with …

By exploiting both the inherent sparsity in the continuous angular domain and the unknown
angular cluster prior, we propose a super-resolution channel estimator for massive multiple …

At a first communication device in a wireless communication network, reference signaling is
received from a second communication device in two or more beams with a same direction …

In this dissertation, the design and fabrication of deep-ultraviolet photodetectors were
investigated based on gallium oxide and its alloys, through the heterogeneous integration …

We focus on the problems of the accurate time delay estimation, the design of training pilots,
and hybrid matrix optimization within the large‐scale antenna array Terahertz (THz) …
