Practical Interference Alignment and Cancellation for MIMO Underlay Cognitive Radio Networks with Multiple Secondary Users
Research Paper / Feb 2014 / MIMO

In the underlay cognitive radio approach, secondary users (SUs) are allowed to transmit their messages as long as the negative impact on the performance of the primary user (PU) is below a certain threshold. This paper considers a MIMO underlay cognitive radio network with a single PU and multiple SUs.
