Power-controlled feedback and training for two-way MIMO channels
Most communication systems use some form of feedback, often related to channel state information. The common models used in analyses either assume perfect channel state information...

Analysis of the pilot contamination effect in very large multicell multiuser MIMO systems for physical channel models
We consider multicell multiuser MIMO systems with a very large number of antennas at the base station. We assume that the channel is estimated by using uplink training sequences, ...

Semi-Blind Spatial Equalisation for MIMO Channels with Quadrature Amplitude Modulation
— Semi-blind spatial equalisation is considered for multiple-input multiple-output (MIMO) systems that employ high-throughput quadrature amplitude modulation scheme. A minimum nu...
