Performance Analysis of MIMO Links With Non‐Isolated Active Antenna Arrays
Microwave and Optical Technology Letters, Volume 67, Issue 8, August 2025.ABSTRACT In this paper, we analyze the performance of non‐isolated active arrays in a multiple‐input multiple‐output (MIMO) system. When ferromagnetic‐type isolators are removed in the transmitter (Tx) chains, the antenna mutual coupling will dynamically change the load impedance seen by the power amplifiers (PAs) at their outputs, which subsequently ...

Performance Enhancement of Indoor VLC Systems Using DPSS‐Based DCO‐GFDM Modulation
IET Communications, Volume 19, Issue 1, January/December 2025.VLC is a promising solution for future wireless communication systems due to its high data rate, wide bandwidth, and enhanced security features. However, challenges such as high PAPR and OOB spectral leakage limit its performance. In this study, we propose the integration of DPSS with DCO‐GFDM to enhance the performance of indoor VLC systems.
