2. 6. Studies of Three Different Methods to Estimate the Up-link Performance of Mobile Phone Antennas

   Author : Sathyaveer Prasad; Peter Händel; Claes Beckman; Jan Carlsson; Högskolan i Gävle; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antenna measurements; mobile phones; total radiated power; reverberation chamber; anechoic chamber; Telia Scattered Field Method; Maximum likelihood Estimator; Telecommunication; Telekommunikation;

   Abstract : Antennas play an important role in determining the overall radio performance for wireless communications. If all other radio components perform according to their specifications, the performance of a mobile phone can be entirely determined by measuring the efficiency of its antenna. READ MORE

4. 7. Dynamically Reconfigurable Architectures for Real-time Baseband Processing

   Author : Chenxin Zhang; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reconfigurable Computing; Coarse-Grained Architecture; Dynamic Reconfiguration; SIMD; VLIW; ASIP; Vector Processor; Baseband Processing; OFDM; MIMO; Channel Estimation; Symbol Detection.;

   Abstract : Motivated by challenges from today's fast-evolving wireless communication standards and soaring silicon design cost, it is important to design a flexible hardware platform that can be dynamically reconfigured to adapt to current operating scenarios, provide seamless handover between different communication networks, and extend the longevity of advanced systems. Moreover, increasingly sophisticated baseband processing algorithms pose stringent requirements of real-time processing for hardware implementations, especially for power-budget limited mobile terminals.

5. 8. Flexible Interleaving Sub–systems for FEC in Baseband Processors

   Author : Rizwan Asghar; Dake Liu; Joseph R. Cavallaro; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Interleaving is always used in combination with an error control coding. It spreads the burst noise, and changes the burst noise to white noise so that the noise induced bit errors can be corrected. READ MORE

6. 9. Array Processing Techniques for Direction of Arrival Estimation, Communications, and Localization in Vehicular and Wireless Sensor Networks

   Author : Marco Antonio Marques Marinho; Alexey Vinel; Henk Wymeersch; Högskolan i Halmstad; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DOA estimation; Array Interpolation; MIMO; Wireless Sensor Networks; Radio Positioning;

   Abstract : Array signal processing in wireless communication has been a topic of interest in research for over three decades. In the fourth generation (4G) of the wireless communication systems, also known as Long Term Evolution (LTE), multi antenna systems have been adopted according to the Release 9 of the 3rd Generation Partnership Project (3GPP).

7. 10. Ultra-Reliable and Resilient Communication Service for Cyber-Physical Systems

   Author : Milad Ganjalizadeh; Marina Petrova; Jens Zander; Petar Popovski; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 5G; availability; cyber-physical systems CPSs ; deep Q-networks DQN ; deep reinforcement learning; distributed learning; machine learning; network slicing; reliability; soft actor-critic SAC ; ultra-reliable low-latency communications URLLC ; wireless communications.; Informations- och kommunikationsteknik; Information and Communication Technology; Datalogi; Computer Science;

   Abstract : Cyber-Physical Systems (CPSs) are becoming ubiquitous in modern society, enabling new applications that rely on the seamless interaction between computing, communication, and physical processes. In this context, ultra-reliable low-latency communications (URLLC) emerges as a crucial element, reliably allowing the real-time exchange of critical data. READ MORE
