1. 1. Flexible wireless receivers : on-chip testing techniques and design for test

   Författare :Ramzan Rashad; Fenghao Mu; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : In recent years the interest in the design of low cost multistandard mobile devices has gone from technical aspiration to commercial essential. Usually, the emerging wireless applications prompt the conception of new wireless standards. The end user wants to access voice, data, and streaming media from single wireless terminal. LÄS MER

3. 2. Reduced Receivers for Faster-than-Nyquist Signaling and General Linear Channels

   Författare :Adnan Prlja; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital data transmission; receivers; decoders; channel modeling; intersymbol interference; ISI; MIMO; Faster-than-Nyquist signaling; complexity reduction; observation models; BCJR algorithm; turbo equalization; iterative detection; channel shortening;

   Sammanfattning : Fast and reliable data transmission together with high bandwidth efficiency are important design aspects in a modern digital communication system. Many different approaches exist but in this thesis bandwidth efficiency is obtained by increasing the data transmission rate with the faster-than-Nyquist (FTN) framework while keeping a fixed power spectral density (PSD).

4. 3. Ifrågasatta företagare : Konkursförvaltares syn på kvinnor och män som företagsgäldenärer under 1900-talet

   Författare :Maria Axelsson; Mats Larsson; Torbjörn Engdahl; Pia Höök; Uppsala universitet; []
   Nyckelord :Social sciences; business bankruptcies; gender perspective; men and women in business; receivers; debtors; Uppsala; business networks; bank contacts; business competence; business characteristics; attitudes towards bankruptcies; bankruptcy causes; principal component analysis; SAMHÄLLSVETENSKAP; ekonomisk historia; Economic History;

   Sammanfattning : The principle purpose of this thesis has been to study and analyse the conception of men and women in business bankruptcy during the 20th century. The analysis is built on a theoretical gender perspective and, combining this view and business and bankruptcy research, the thesis has focused on five themes: business networks, bank contacts, business competence, business characteristics and finally bankruptcy causes.

   Sammanfattning : The wireless market is developing very fast today with a steadily increasing number of users all around the world. An increasing number of users and the constant need for higher and higher data rates have led to an increasing number of emerging wireless communication standards. LÄS MER

7. 5. CMOS Parallel-Sampling Receivers

   Författare :Henrik Johansson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : As the processing capacity of the microelectronic circuits increases, the demands on the interconnects will also increase. Hence, there is a need for higher bandwidth to the chips. This dissertation discusses the possibilities to improve the input data rate to CMOS integrated circuits, which is the most common integrated circuit technology today. LÄS MER
