Spectrum management and power allocation in MIMO cognitive networks
Cognitive radio (CR) techniques improve the spectrum utilization by exploiting temporarily-free frequency bands (i.e., in the time domain). The spectrum utilization can be boosted...

Generalized Design of Multi-User MIMO Precoding Matrices
In this paper we introduce a novel linear precoding technique. The approach used for the design of the precoding matrix is general and the resulting algorithm can address several o...
