26. Successive Interference Cancellation in DS-CDMA Systems
Sammanfattning : There is every indication that direct-sequence code division multiple access (DS-CDMA) will be one of the multiple access schemes for the third generation wireless mobile systems. CDMA is a flexible multiple access method suitable for supporting many new services (speech, data, video, etc), which are becoming increasingly important for mobile communications. LÄS MER
27. Design and analysis of digital receivers
Sammanfattning : This thesis consists of a summary and nine included papers, grouped into three parts. There is one journal paper, three reports written in the style of articles, four conference papers and one paper submitted to a conference. LÄS MER
28. Bit loading and precoding for MIMO communication systems
Sammanfattning : This thesis considers the joint design of bit loading, precoding and receive filters for a multiple-input multiple-output (MIMO) digital communication system. Both the transmitter and the receiver are assumed to know the channel matrix perfectly. It is well known that, for linear MIMO transceivers, orthogonal transmission (i.e. LÄS MER
29. Techniques for the determination of the optimal performance of high resolution computerised tomography
Sammanfattning : Techniques to deternine the optimal performance of high resolution computerised tomography (CT) has been studied, that is, optimal data collection parameter settings for the imaging task at issue and its detectability limits.Generally, CT is an X-ray based non-destructive testing method that was developed for medical purposes in the seventies and introduced for industrial applications the latter half of the eighties.

30. Channel Shortening in Wireless Communication
Sammanfattning : The concept of Channel Shortening (CS) is a well-known technique that has a rich history over 40 years. CS transfers linear vector channels such as multi-input multi-output (MIMO) and intersymbol interference (ISI) channels into ``shortened'' versions, for the purpose of reducing demodulation-complexity and improving data-transmission performance.
