Intelligent CSI feedback method for fast time-varying FDD massive MIMO system
Published 2021-07-01“…In the frequency division duplexing (FDD) massive multiple-input multiple-output (MIMO) system, the channel state information (CSI) matrix existed noise caused by the wireless channel interference and the time correlation caused by Doppler shift.Because of these effects, the communication system couldn’t guarantee the requirements of reliability and low delay.An intelligent CSI feedback method was adopted.The convolutional neural network (CNN) and batch normalization (BN) network was used to extract the noise in the CSI matrix and learned the spatial structure of the channel.The time correlation between the CSI matrices through the attention mechanism was extracted to improve the accuracy of CSI reconstruction.The data was generated by the standard fast time-varying channel model simulation to train the network offline.System simulation and analysis show that the proposed method can effectively suppress the influence of noise and extract the time correlation caused by Doppler.Compared with the traditional CSI compression feedback algorithm and CsiNet algorithm, the proposed method has better NMSE and cosine similarity performance.…”

Fuzzy Adaptive Prescribed Performance Control for MIMO Uncertain Chaotic Systems in Nonstrict Feedback Form
Published 2014-01-01“…For the prescribed performance bounds, we mean that the tracking error should converge to a predefined arbitrarily small set, with convergence rate no more than a prescribed value. A novel output error transformation is introduced to transform the original constrained system into an equivalent unconstrained one, and it is proved that the stabilization of the unconstrained system is sufficient to solve the problem. …”

Influence of the Pre-compression Amount of the Spring Excitation Segment on the Meshing Performance of the Spring Clutch
Published 2015-01-01“…The self-excitation of the spring clutch is realized through the pre-compression between the excitation coils at either end of the spring and housing to generate frictional torque to energize the spring.The pre-compression amount of excitation coils at either end of the spring has a great impact on the binding property and lifetime of spring clutch.The spring clutch dynamics model is established by using the finite element analysis method.On ABAQUS platform,the speed synchronization of high speed spring clutch output shell and the input shell,the Mises stress and radial displacement of spring under different pre-compression are solved,and then the pre-compression amount condition of the self-exciting meshing of the spring clutch is obtained,and it is compared with the critical amount of pre-compression of clutch obtained by the analytic solution.Besides,the finite element analysis results show that the steady state stress distribution of spring exhibits M shape,that is,the transition coils have peak stress while the middle coils have uniform stress distribution.The basis for optimal design of spring clutch can be provided.…”

Low-power transmission method for uplink millimeter-wave massive MIMO-NOMA system based on GSIC
Published 2023-01-01“…The combination of non-orthogonal multiple access (NOMA) and millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) can meet the requirements for huge throughput and massive connectivity in future wireless communication network.The total system power minimization for uplink mmWave massive MIMO-NOMA was studied, and a novel framework for a hybrid beamforming mmWave massive MIMO-NOMA uplink transmission system was proposed based on group-level successive interference cancellation (GSIC).Specifically, users were grouped according to channel gain, intergroup users being served by NOMA and intra group users being served by space division multiple access.By designing analog beamforming matrices for different groups and performing joint optimization for digital beamforming and power control, a parallel iterative algorithm was proposed to solve the optimization problem.Simulation results show that the proposed method outperforms the conventional mmWave massive MIMO-NOMA based on clustering and user-level SIC in terms of total power consumption.…”

Policy-focused Stance Detection in Parliamentary Debate Speeches
Published 2022-07-01“…We find that it is possible to identify the policies under discussion using features derived from the speeches, and that incorporating motion-dependent debate modelling, previously used to classify speech sentiment, also improves performance in the classification of policy preferences. We analyse the output of the best performing system, finding that discriminating features for the task are highly domain-specific, and that speeches that address policy preferences proposed by members of the same party can be among the most difficult to predict. …”
