Cooperative Secondary Beam Selection for Cognitive Multiuser MIMO Transmission With Random Beamforming

This paper studies the performance of a random beamforming-based secondary MIMO system, which coexists with a primary system with single primary transmitter (PT) and single primary receiver (PR). To ensure the performance requirement of the primary system, i.e., the received signal-to-interference-p...
