div>A novel channel model has been proposed for mobile millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) communications to evaluate the effect of end-user mobility. In this model the variance of number of clusters and number of rays generated from each cluster is taken into...

In addition, the size of the magnet in the x-direction determines whether the transverse magnetic field in the beam channel is uniform, this requires that the size in the x-direction should not be too small9. At the same time, considering the cost and the weight of the whole tube, the...
modern wireless communication, the orbital angular momentum (OAM) beam is considered as an important technology. Some considerable efforts have been devoted to using this technology for channel capacity enhancement as much as possible. Nowadays, programm
single channel denoising(Spectral Subtraction, Subspace, Iterative Wiener) We use an object-oriented approach to abstract the details of specific algorithms, making them easy to compare. Each algorithm can be tuned through optional parameters. We have tried to pre-set values for the tuning parameters...

When using whitened data for the covariance computation and subsequent analysis, the forward model needs to be computed from the balanced sensor array. MNE-Python combines different sensor or channel types through pre-whitening of the covariance matrix, leadfield, and data. Furthermore, the cross-...
and channel combinations. Another challenge involves system-level tradeoffs between performing beamforming in the radio frequency (RF) and/or digital baseband domain. All these activities are best done early in the design process. You can use MATLAB and Simulink®to assess the impact of RF effect...
In an effort to improve spatial resolution, more recent fractal mode images were recorded with a 20 × objective and processed by ImageJ software which introduces a Gaussian band-pass filter in the Fourier (spatial frequency) domain, thereby improving contrast (Supplementary Fig. 8). With th...
Vortex beam was further applied in millimeter-wave domain to achieve as dual-channel 60 GHz communications, where 8-Gbit/s and 4-Gbit/s wireless link were realized using different OAM modes10. For vortex beam generation, spiral phase plate11 and holographic diffraction gratings12 are widely ...
