Practical Interference Alignment and Cancellation for MIMO Underlay Cognitive Radio Networks with Multiple Secondary Users

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.

As live sports migrates from traditional broadcast to digital platforms, streaming is redefining how leagues, networks, and tech providers engage audiences and generate revenue. This transition brings both opportunity and complexity—from fragmented rights and shifting viewer expectations to significant technical demands around latency, scalability, and quality.
