Perturbation-Based Nulling Control Beamforming With Measured Element Radiation Patterns for MU-mMIMO
Publikováno v:
IEEE Open Journal of Vehicular Technology, Vol 5, Pp 1273-1293 (2024)
A perturbation-based nulling control beamforming (PNCB) scheme is proposed to effectively mitigate multi-user interference (MUI) in multi-user massive multiple-input multiple-output (MU-mMIMO) systems. This is achieved through the precise alignment o
