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...

Low-Complexity MU-MIMO Nonlinear Precoding Using Degree-2 Sparse Vector Perturbation
Abstract—Multiuser multiple-input multiple-output (MUMIMO) nonlinear precoding techniques face the problem of poor computational scalability to the size of the network. In this p...

Broadcast Channels with Delayed Finite-Rate Feedback: Predict or Observe?
Most multiuser precoding techniques require accurate transmitter channel state information (CSIT) to maintain orthogonality between the users. Such techniques have proven quite fr...
