1. 1. Audibility & Preference of DA Overload Associated with True Peak : Investigation of claims made against overload prevention

   University essay from Luleå tekniska universitet/Musik, medier och teater

   Author : Mattias Strand; [2023]
   Keywords : true peak; mastering; inter-sample; intersample; peaks; peaking; overload; digital to analog; da; loudness; clipping; truncation; square wave;

   Abstract : The conversion of audio from the digital to analog domain has the potential to result in distortion due to converter overload. This occurs because some peaks in the signal cannot be defined digitally and only become problematic during the conversion into the analog domain, exceeding the level that can be represented by the converter, causing it to overload.

3. 2. 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.

4. 3. Joint CFR and DPD optimization for 5G Digital Front Ends

   University essay from Lunds universitet/Matematik LTH

   Author : Gustav Olsson; [2023]
   Keywords : Crest Factor Reduction; Digital Pre-Distortion; Power Amplifier; Parameter Optimization; 5G; Base Station; Memory Polynomial; Technology and Engineering;

   Abstract : This thesis project investigates the topic of joint optimization for crest factor reduction and digital predistortion blocks, which are used for digital correction of analogue impairments in digital radio front ends. The work first investigates the effects of joint parameter variation of the above blocks on the global performance and computational cost of the digital chain, given reference CFR and DPD algorithms.

5. 4. Design of auxiliary communication for audio between computers and DSPs : Programming and optimization of computational resources

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Eriksson Janze Oscar; [2023]
   Keywords : DSP; Audio-communication; Auxiliary; AUX; phone connector; USB-audio; STM32; ADC; AD-converter; filterbank; hearing aid; signalprocessor; ljudkommunikation; ljudkabel; AUX; USB-ljud; STM32; hjälpmedel; ADC; analog-till-digital-omvandlare;

   Abstract : This thesis report is about designing a prototype and establishing audio communication between a computer and Digital Signal Processor (DSP) using two preamp circuits using both auxiliary and USB connection. The paper gives the reader an overview on how audio is transmitted from a computer, through the system and to the desired output. READ MORE

6. 5. Power Estimation Tool for Digital Front-End 5G Radio ASIC

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Rajnandini Bhutada; [2023]
   Keywords : 5G; ASIC; DFE; Carrier Aggregation; Digital Pre-Distortion; Downlink; Uplink; Power Consumption; Power Model; Yield Analysis.;

   Abstract : Application Specific Integrated Circuits (ASICs) are critical to delivering on 5G’s promises of high speed, low latency, and expanded capacity. Digital Front-End (DFE) ASICs are particularly important components because they enhance crucial signal processing activities. READ MORE
