—We consider multi-user MIMO broadcast channels with limited feedback. A recently proposed linear precoding technique, regularized block diagonalization (RBD), is used to mitigat...
Interference alignment is a transmission technique for exploiting all available degrees of freedom in the symmetric frequency- or time-selective interference channel with an arbit...
Feedback of channel state information (CSI) is necessary to achieve high throughput and low outage probability in multiuser multiantenna systems. There are two types of CSI: direc...
