Artificial Noise Elimination: From the Perspective of Eavesdroppers
TL;DR: A class of efficient null-space elimination (NSE) schemes are conceived in order to reduce the number of receive antennas while enhancing the detection quality compared to original ZFE, demonstrating that NSE can provide more robust performance for eavesdroppers over ZFE with lower hardware requirements as well as moderate complexity increase.

Subcarrier grouping with environmental sensing for MIMO-OFDM systems over correlated double-selective fading channels
TL;DR: An adaptive subcarrier grouping scheme is proposed to satisfy the preset capacity loss threshold by adjusting grouping size with the sensed environmental information and mobile velocity and results show that to achieve a better system capacity, a sparse scattering, lower signal-to-noise ratio, and lower velocity are matched with larger sub carrier group size.

Performance Evaluation of Virtual MIMO Multi-User System in a Measured Indoor Environment at 5 GHz
TL;DR: The results show that virtual MIMO in many cases is desirable for capacity improvement and that capacity improvement is mostly due to the rms delay spread and special correlation reduction than the $$K$$K-factor reduction.

Handover Strategy Based on Side Information in Air-Ground Integrated Vehicular Networks
TL;DR: A novel handover strategy based on side information of the ADS-B for AGVN using single HAPS as air base station to assist cellular network with multiple users is proposed and simulation results show the fully use of side information can increase the capacity of theAGVN.

Mean Capacity of Spatially Semi-Correlated MIMO Fading Channel
TL;DR: This study proposes an iterative channel covariance (ICC) matrix using a matrix splitting technique with a guaranteed zero correlations coefficient in the case of the downlink correlated MIMO channel, to maximize the mean capacity of multiple-input multiple-output (MIMO) systems.
