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.

In a new insight paper commissioned by InterDigital, CCS Insights details why energy efficiency is increasingly important in the video and media ecosystem, and introduces InterDigital’s cutting edge Pixel Value Reduction technology as an exciting solution to reduce energy consumption and extend watch time, enabling sustainability at scale across billions of devi…
