Over-The-Air Phase Calibration of Spaceborne Phased Array for LEO Satellite Communications
Wei Zhang, Ding Chen, Bin Zhou
To avoid the unpredictable phase deviations of the spaceborne phased array (SPA), this paper considers the over-the-air (OTA) phase calibration of the SPA for the low earth orbit (…
SIMRP: Self-Interference Mitigation Using RIS and Phase Shifter Network
Zhang Wei, Chen Ding, Bin Zhou +2
Strong self-interference due to the co-located transmitter is the bottleneck for implementing an in-band full-duplex (IBFD) system. If not adequately mitigated, the strong interfer…
Phases Calibration of RIS Using Backpropagation Algorithm
Wei Zhang, Bin Zhou, Tianyi Zhang +2
Reconfigurable intelligent surface (RIS) technology has emerged in recent years as a promising solution to the ever-increasing demand for wireless communication capacity. In practi…
Channel Estimation Considerate Precoder Design for Multi-user Massive MIMO-OFDM Systems: The Concept and Fast Algorithms
Liu Junkai, Jiang Yi
The sixth-generation (6G) communication networks target peak data rates exceeding 1Tbps, necessitating base stations (BS) to support up to 100 simultaneous data streams. However, s…
