1. Iterative receivers with channel estimation for MIMO and multi-user OFDM systems
Sammanfattning : The traffic in wireless networks has been showing an exponential growth over the last decade. In order to meet the demand, and support a continuation of this growth, the scarce radio resources need to be efficiently used. LÄS MER
2. Simplified Graphical Approaches for CDMA Multi-User Detection, Decoding and Power Control
Sammanfattning : The individual optimal detector for code-division multiple-access (CDMA) systems is based on the marginal a posteriori distribution of the transmitted bits. The marginalization is in general hard since a summation is required, which grows exponentially in scope with the number of active users. LÄS MER
3. Interference Rejection in Wireless Communication Systems
Sammanfattning : This thesis is concerned with the problem of interference rejection in wireless communication systems. Different solutions are proposed, depending on the type of system under study and the amount of knowledge available about the signal and the propagation environment. LÄS MER
4. Joint ML multi user detection of block coded CDMA over the AWGN channel using A*
Sammanfattning : .... LÄS MER
5. Estimation and detection of transmission line characteristics in the copper access network
Sammanfattning : The copper access-network operators face the challenge of developing and maintaining cost-effective digital subscriber line (DSL) services that are competitive to other broadband access technologies. The way forward is dictated by the demand of ever increasing data rates on the twisted-pair copper lines. LÄS MER
