1. 1. 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.

3. 2. 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.

   Sammanfattning : The market for Wi-Fi receiver designs for latest Wi-Fi standards, that cover RF bands in the 2.4 GHz, 5 GHz and 6 GHz spectrum, require increasingly stringent power consumption limitations as more of the market is driven towards battery-powered devices. LÄS MER

5. 4. “Those were the days?” : A qualitative study on the elderly’s acceptance of the digital world in Finland

   Master-uppsats, Uppsala universitet/Institutionen för kvinnors och barns hälsa

   Författare :Sampo Sorvisto; [2023]
   Nyckelord :Elderly; digitalisation; quality of life; society; digital services; e-health; inclusivity;

   Sammanfattning : This study aims to discover how self-supported elderly in Finland experience the move towards a digital society and how this change affects their daily lives. As the proportion of the elderly compared to younger generations changes, so does the need for digital services catering to this population group. LÄS MER

7. 5. Digitalising the Restaurant Visit: An Experimental Study of How QR Codes and Waiting Staff in the Ordering Process Affect Customer Satisfaction

   C-uppsats, Handelshögskolan i Stockholm/Institutionen för marknadsföring och strategi
