    Sammanfattning : In the near future, the number of connected mobile devices and data-rates are expected to dramatically increase. Demands exceed the capability of the currently deployed (4G) wireless communication systems. LÄS MER

  3. 12. 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.

  4. 13. Quantization and Noise-Shaped Coding for High Efficiency Transmitter Architectures

    Författare :Ulf Gustavsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Software Defined Radio; Quantization; damped Gauss-Newton; Pulse Density Modulation; Noise-Shaped Coding; ΣΔ-Modulators; Power Amplifier;

    Sammanfattning : Three driving parameters in the development of transmitter technologies for wireless communication today is: energy efficiency, flexibility and footprint reduction. This thesis investigates the use of 1-bit oversampled signal representation, mainly as a power efficiency enhancement technique for the transmitter, but also as a path toward reduced footprint and increased flexibility.

  5. 14. Efficient Compilation for Application Specific Instruction set DSP Processors with Multi-bank Memories

    Författare :Joar Sohl; Dake Liu; Krzysztof Kuchcinski; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Modern signal processing systems require more and more processing capacity as times goes on. Previously, large increases in speed and power efficiency have come from process technology improvements. However, lately the gain from process improvements have been greatly reduced. LÄS MER
