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.

Media over Wireless: Networks for Ubiquitous Video

To realize the objectives of Integrated Sensing and Communication (ISAC) in 6G, there is a need to introduce new functionalities in 6G core (6GC) architecture that are dynamic and resource-efficient. In ISAC, sensing signals are used by a Sensing Receiver (SRx) to measure and report Sensing Data Points (SDPs) to the network. However, a direct approach involving …
