Unlike traditional MIMO systems, SUs may not havethe luxury of knowing the channel state information (CSI)on the links to PUs. This presents a key challenge for asecondary transmitter to steer interference away from primaryreceivers. In this paper, we consider three scenarios,namely when the secondary transmitter has complete,
