Effects of Non-Ideal Channel Feedback on Dual-Stream MIMO-OFDMA System Performance
— In this paper we analyze the downlink OFDMA system-level performances of a 2x2 dual-stream MIMO multiuser transmission scheme under the assumptions of partial and noisy channel...

Enhanced multiuser random beamforming: dealing with the not so large number of users case
We consider the downlink of a wireless system with an M-antenna base station and K single-antenna users. A limited feedback-based scheduling and precoding scenario is considered th...

A Low-Complexity Precoder for Large Multiuser MISO Systems
—In this paper, we consider the problem of precoding in large multiuser MISO systems, where by ‘large’ we mean i) large number of transmit antennas (Nt) at the base station o...
