1. 1. Analog mixed signal front-end for Torque signal processing : A theoretical noise analysis and signal-chain evaluation

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Jesper Jansson; Wilhelm Nordgren; [2023]
   Keywords : Torque sensor; noise analysis; signal processing; analog-to-digital conversion; Momentgivare; brusanalys; signalbehandling; analog-till-digital omvandling;

   Abstract : High precision tightening of nuts and bolts together with traceability are important in many industrial assembly lines. To achieve this the nutrunner needs to accurately measure the torque which is applied to the nut, process the signal and provide the information to the controller that controls the tightening process.

   Abstract : Matched frequency responses are a fundamental starting point for a variety ofimplementations for microphone arrays. In this report, two methods for frequencyresponse-calibration of a pre-assembled microphone array are presented andevaluated. READ MORE

4. 3. Real-time Autofocus Algorithm in Laser Speckle Contrast Imaging

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Giovanni Russo; [2023]
   Keywords : Laser speckle contrast imaging; Autofocus; Blind image sharpness assessment; Speckle noise; Perimed’s Perfusion Speckle Imager;

   Abstract : Microcirculation is defined as the blood flow in the smallest blood vessels. Laser speckle contrast imaging (LSCI) is a full field imaging technique that provides instantaneous 2-D perfusion maps of illuminated tissues based on speckle contrast. READ MORE

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

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Midhat Rizvi; Khaled Al-Khateeb; [2023]
   Keywords : 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;

   Abstract : 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.

6. 5. Energy-Efficient Fixed-Coefficient FIR Filters for Millimeter-Wave Radios

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Erik Lundell; Gustav Molin; [2023]
   Keywords : Technology and Engineering;

   Abstract : With the introduction of millimeter-wave antenna arrays in 5G base-stations and ever-increasing data volumes, the power consumption of the signal processing in digital radio systems has increased over the last decade. This, combined with increased cost and environmental awareness, has put focus on power optimization. READ MORE
