1. Analysis of Relay Channels and Improved Iterative Decoders for Turbo-Coded Decode-and-Forward Relay Channels
Sammanfattning : Three-node relay channels which consist of a source, a relay and a destinationare considered in this thesis. In the first part, an uncoded relay channelis studied. LÄS MER
2. Interference Cancellation for DS/CDMA Systems in Flat Fading Channels
Sammanfattning : This thesis investigates interference cancellation in direct-sequence codedivision multiple access (DS/CDMA) systems that support multiple data rates.Two approaches for implementing multiple data rates are considered. Oneis the use of mixed modulation. The second is the use of parallel channels. LÄS MER
3. Rate adaption for progressively encoded video over fading AWGN channels
Sammanfattning : With the increased capacity of the Internet it is possible to use it for real-time multimedia applications, such as video conferences. There is also an increasing interest in using Internet technology in cellular networks, such as mobile phones. LÄS MER
4. Maximum likelihood sequence detection by using the SA(B,C) algorithm : state partition methods
Sammanfattning : .... LÄS MER
5. Physical layer optimization for transportation of scalable media over AWGN channels
Sammanfattning : This thesis presents research results on how the physical layer can aid in the delivery of scalable media. The thesis focuses on wireless links (point-to-point and broadcast) due to their lower capacity. LÄS MER
