Winter Storm Induced Turbulent Structure Alteration Triggers Sediment Export From an Abandoned Subaqueous Delta

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Winter storms present a major erosional hazard to subaqueous deltas globally, but the associated dynamic mechanisms are still not well understood. Using high‐resolution in situ data collected over a 3‐week period in the abandoned Yellow River subaqueous delta, this study employs three‐dimensional quadrant analysis to examine turbulent ...

Analysis of MIMO Receiver Using Generalized Least Squares Method in Colored Environments

Journal of Computer Networks and Communications, 2014
The classical detection techniques for multiple-input multiple-output (MIMO) systems are usually designed with the assumption that the additive complex Gaussian noise is uncorrelated. However, for closely spaced antennas, the additive noise is correlated

A low complexity precoding based on weighted two diagonal iteration in massive MIMO system

Dianxin kexue, 2018
In massive MIMO systems,with the increase of the number of users and antennas,the complexity of the downlink zero forcing (ZF) precoding increases due to the existence of large matrix inversion.In order to reduce the complexity,an improved weighted two ...
