Generation of High Energy-Efficiency Perfect Gaussian Integer Sequences and OTFS Pilot Design

Tongxin xuebao
To enhance the channel estimation accuracy of orthogonal time frequency space (OTFS) systems in high-mobility scenarios, a novel pilot design scheme based on high-energy-efficiency perfect Gaussian integer sequences (PGIS) was proposed.

HOPFNet: An End-to-End CSI Acquisition Method for FDD Massive MIMO Systems

IEEE Open Journal of Vehicular Technology
In massive multiple-input multiple-output (MIMO) systems utilizing the frequency-division duplex (FDD), conventional methods for acquiring downlink channel state information (CSI) lead to high computational complexity and heavy feedback overheads.

Non-Orthogonal Pilot Designs for Joint Channel Estimation and Collision Detection in Grant-Free Access Systems

IEEE Access, 2018
In this paper, we consider a densely deployed phantom cell system providing a low latency network for massive connectivity. Non-orthogonal pilot designs serve as a promising solution to support a large number of users, but fast collision detection at the

Investigation of optical and electrophysical properties of Mn4Si7 coatings of different thickness

Фізика і хімія твердого тіла
Studies of Mn4Si7 coatings of different thicknesses have shown that magnetron deposition practically does not change the composition of the coating in comparison with the composition of the target. The technology and basic modes of creating the necessary
