   Sammanfattning : Driven by the exponential growth in mobile broadband subscriptions and mobile data traffic, transport capacity of mobile networks has to be enhanced accordingly, including wireless backhaul and the emerging fronthaul networks. Utilizing wide bandwidth is the most straightforward way to capacity upgrade. LÄS MER

4. 8. Studies on Design and Implementation of Low-Complexity Digital Filters

   Författare :Henrik Ohlsson; Lars Wanhammar; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-complexity digital filters; lattice wave digital filters LWDFs ; digital down converter DDC ; analog-to-digital converters ADCs ; Signal processing; Signalbehandling;

   Sammanfattning : In this thesis we discuss design and implementation of low-complexity digital filters. Digital filters are key components in most digital signal processing (DSP) systems and are, for example, used for interpolation and decimation. LÄS MER

5. 9. Digital Baseband Modeling and Correction of Radio Frequency Power Amplifiers

   Författare :Per Landin; Peter Händel; Magnus Isaksson; Wendy Van Moer; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Aspects related to behavioral modeling and correction of distortions for radio frequency (RF) power amplifiers (PAs) are treated in the thesis.    When evaluating the performance of a behavioral model it is important to, first of all, use an evaluation criterion, and second, make sure that the criterion actually tells something about the behavior one wishes to describe.

7. 10. Towards a Functional Programming Language for Baseband Signal Processing

   Författare :Anders Persson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; signal processing; domain specific languages; functional programming; code generation;

   Sammanfattning : Developing software for resource constrained embedded systems is a daunting task. In addition to getting the functionality right, a programmer must consider several non-functional properties, including data layout, the target memory hierarchy, concurrency and parallelism. LÄS MER
