  1. 1. Design of superconductor digital circuits for a 30 GHz DSP and for interface to qubits

    Författare :Samuel Intiso; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VHDL; thermal; RSFQ; noise temperature; Time-delay Optimization; WCDMA; Hierarchycal memory; DSP;

    Sammanfattning : Superconducting digital technology based on Rapid Single Flux Quantum logic (RSFQ) is a digital technology characterized by high speed, low power consumption and low operational temperatures. RSFQ is attractive for many applications and in particular for high frequency Digital Signal Processing (DSP) and for digital control of mK devices like superconducting qubits. LÄS MER

  3. 2. Machining Monitoring and Control : Based on Parametric Modelling

    Författare :Mats Bejhem; KTH; []
    Nyckelord :Machining Control; tool condition monitoring; in-process dynamic stability monitoring and control; optimisation of cutting conditions; MC; DSP; TCM; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The objective of this work was the development of aMachining Control prototype system for turning, whichintegrates three fundamental aspects of Machining Controltechnology: Monitoring, Control and Optimisation. MachiningControl refers to the detection and automatic handling ofdisturbances in machining processes. LÄS MER

  4. 3. DSP-based Coherent Optical Systems : Receiver Sensitivity and Coding Aspects

    Författare :Miu Yoong Leong; Sergei Popov; Gunnar Jacobsen; Soren Forchhammer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : User demand for faster access to more data is at a historic high and rising. One of the enabling technologies that makes the information age possible is fiber-optic communications, where light is used to carry information from one place to another over optical fiber. LÄS MER

  5. 4. Design of programmable multi-standard baseband processors

    Författare :Anders Nilsson; Dake Liu; Gerhard Fettweis; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DSP; baseband processor; ASIP; Computer engineering; Datorteknik;

    Sammanfattning : Efficient programmable baseband processors are important to enable true multi-standard radio platforms as convergence of mobile communication devices and systems requires multi-standard processing devices. The processors do not only need the capability to handle differences in a single standard, often there is a great need to cover several completely different modulation methods such as OFDM and CDMA with the same processing device.

  7. 5. Linear Interpolation D/A Converter Applied to Direct Digital RF Modulators

    Författare :Zhou Yijun; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; Electrical engineering; SOC.; quadrature modulator; interpolation; filter; DSP; CMOS; DAC;

    Sammanfattning : This thesis deals with techniques for the full integration of radio frequency (RF) transmitter with CMOS technology. The theory and implementation of high performance digital-to-analog converters (DACs) for radio frequency (RF) transmitters have been studied. A linear interpolation DAC architecture is proposed.
