1. 1. Physical Layer Security for MIMOTransmission of Short PacketCommunications

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Varun Duvva; Bharath Reddy Anugu; [2024]
   Keywords : Physical Layer Security; Multiple-Input Multiple-Output; Short Packet communication; Maximum Ratio Combining; Maximum Ratio Transmission; and Beamforming;

   Abstract : This thesis explores the practical application of Physical Layer Security (PLS) inMultiple-Input Multiple-Output (MIMO) systems, particularly focusing on ShortPacket Communication (SPC). The aim is to enhance the security of wireless com-munications against eavesdropping threats. READ MORE

3. 2. Using search based methods for beamforming

   University essay from Uppsala universitet/Avdelningen för systemteknik

   Author : Adam Bergman Karlsson; [2024]
   Keywords : Beamforming; Artificial Intelligence; AlphaZero; Radio Resource Management; Monte Carlo Tree Search;

   Abstract : In accommodating the growing global demand for wireless, Multi-User Multiple-Input and Multiple-Output (MU-MIMO) systems have been identified as the key technology. In such systems, a transmitting basestation serves several users simultaneously, increasing the network capacity. READ MORE
