Energy and spectral efficiency of leakage-based precoding for large-scale MU-MIMO systems

We study the capacity performance of signal-toleakage- and-noise ratio precoding scheme (SLNR-PS) for largescale multiuser multiple-inputmultiple-output systems.We derive capacity bounds of SLNR-PS when the number of base station antennas N is large. A trade-off between energy efficiency (EE) a...
