Channel Estimation for Movable Antenna Communication Systems: A Framework Based on Compressed Sensing
Zhenyu Xiao, Songqi Cao, Lipeng Zhu +3
Movable antenna (MA) is a new technology with great potential to improve communication performance by enabling local movement of antennas for pursuing better channel conditions. In…
Delay Doppler Transform
Xiang-Gen Xia
This letter is to introduce delay Doppler transform (DDT) for a time domain signal. It is motivated by the recent studies in wireless communications over delay Doppler channels tha…
Robust Multidimentional Chinese Remainder Theorem for Integer Vector Reconstruction
Li Xiao, Haiye Huo, Xiang-Gen Xia
The problem of robustly reconstructing an integer vector from its erroneous remainders appears in many applications in the field of multidimensional (MD) signal processing. To addr…
Multiuser Communications with Movable-Antenna Base Station: Joint Antenna Positioning, Receive Combining, and Power Control
Zhenyu Xiao, Xiangyu Pi, Lipeng Zhu +2
Movable antenna (MA) is an emerging technology which enables a local movement of the antenna in the transmitter/receiver region for improving the channel condition and communicatio…
Proactive Content Caching Scheme in Urban Vehicular Networks
Biqian Feng, Chenyuan Feng, Daquan Feng +2
Stream media content caching is a key enabling technology to promote the value chain of future urban vehicular networks. Nevertheless, the high mobility of vehicles, intermittency…
A Graph-Based Collision Resolution Scheme for Asynchronous Unsourced Random Access
Tianya Li, Yongpeng Wu, Wenjun Zhang +2
This paper investigates the multiple-input-multiple-output (MIMO) massive unsourced random access in an asynchronous orthogonal frequency division multiplexing (OFDM) system, with…
Precoder Design for Massive MIMO Downlink with Matrix Manifold Optimization
Rui Sun, Chen Wang, An-An Lu +2
We investigate the weighted sum-rate (WSR) maximization linear precoder design for massive multiple-input multiple-output (MIMO) downlink. We consider a single-cell system with mul…
