   Sammanfattning : 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. LÄS MER

3. 2. Evaluation and Optimization of LTE-V2X Mode 4 under Aperiodic Messages of Variable Size

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Md Mamunur Rashid; [2023]
   Nyckelord :LTE-V2X; aperiodic; variable size; CAM; Technology and Engineering;

   Sammanfattning : Vehicular networks connect vehicles for improved road safety and efficiency with the assistance of wireless information exchange. Vehicular networks are based on the frequent broadcast of awareness messages referred to as CAM (Cooperative Awareness Messages) or BSM (Basic Safety Message) in the ETSI and SAE standards, respectively.

   Magister-uppsats, Lunds universitet/Institutionen för informatik

   Författare :Praveen Surendranath; Roopak Ayikkara Kizhakkayil; [2023]
   Nyckelord :PMS; employee; performance; evaluation; satisfaction; Business and Economics;

   Sammanfattning : An effective performance management system plays a crucial role in fostering employee engagement and productivity, which are essential for an organization's success. Employee satisfaction is one of the most important factors. However, the critical aspect of employee satisfaction has been largely overlooked in the existing literature. LÄS MER

7. 5. Digital Front End Algorithms for Sub-Band Full Duplex

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Midhat Rizvi; Khaled Al-Khateeb; [2023]
   Nyckelord :Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

   Sammanfattning : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.
