MIMO Assisted Networks Relying on Intelligent Reflective Surfaces

Understand

Intelligent reflective surfaces (IRSs) are invoked for improving both spectral efficiency (SE) and energy efficiency (EE).

• Specifically, an IRS-aided multiple-input multiple-output network is considered, where the performance of randomly roaming users is analyzed by utilizing stochastic geometry tools.
• As such, to distinguish the superposed signals at each user, the passive beamforming weight at the IRSs and detection weight vectors at the users are jointly designed.
• As a benefit, by adopting a zero-forcing-based design, the intra-cell interference imposed by the IRS can be suppressed.
