  1. 1. 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.

    Keywords : Delay-Locked Loop; DLL; Edge-Combining; EC; EC DLL; Edge-Combining Delay-Locked Loop; spurious tone calibration; spurs calibration; spurious tones compensation; spurs compensation; Technology and Engineering;

    Abstract : 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. READ MORE

  4. 3. Practical Analysis of the Giskard Consensus Protoco

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

    Author : Leon Sandner; [2023]
    Keywords : Distributed Ledger; Blockchain; Consensus Protocol; Giskard; Hyperledger Sawtooth; Distribuerade Huvudbok; Blockchain; Konsensus; Giskard; Hyperledger Sawtooth;

    Abstract : Consensus protocols are the core of modern blockchain systems, such as the Bitcoin, Ethereum, and Algorand networks. Thanks to these protocols, participants in a blockchain network can reach consensus on which blocks to add to a blockchain, to have a consistent chain of blocks in the whole network. READ MORE

  5. 4. Attaining Product Level Forward Traceability for Textile & Fashion : Using Block Chain based Traceability Solutions

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Muhammad Hassan Khalid; [2022]
    Keywords : Forward traceability; Backward traceability; Granularity; Block chain technology; Traceability technologies; Customer privacy;

    Abstract : The purpose of this thesis is to explore how to enable forward traceability of textile and fashion products at product level, using BC based traceability solutions. The study finds that within TC industry, forward traceability using available technologies (RFIDs, NFCs, QR codes ) is technically possible, however there could be impending regulatory, legal, technical implications of using these technologies.

  6. 5. 64-point FFT Instruction Implementation and Evaluation on a Microcode Programmable Processor

    University essay from Linköpings universitet/Institutionen för systemteknik; Linköpings universitet/Tekniska fakulteten

    Author : Yongjun Liu; Zejun Huang; [2022]
    Keywords : FFT; Instruction design;

    Abstract : Fast Fourier Transform is an efficient algorithm for computing the Discrete Fourier Transform (DFT) and one of the most important algorithms used in many digital signal processing applications over decades. This thesis presents an efficient implementation method of a 32-bit complex number 64-point FFT instruction on a micro-programmable processor. READ MORE
