1. 11. Evaluation of MIMO Non- Stationarity

   University essay from KTH/Signalbehandling

   Author : Omar Aldayel; [2011]
   Keywords : ;

   Abstract : The transmission performance of MIMO systems can be highly improved under stationary channel conditions where the channel statistics are constant. Unfortunately, mobile radio channels are not stationary all the time. Instead, they are stationary for finite time durations, so-called the stationarity regions. READ MORE

4. 13. Modeling church services supply and performance, using geographically weighted regression

   University essay from Ämnesavdelningen för samhällsbyggnad

   Author : Xin HE; [2009]
   Keywords : church services; spatial non-stationarity; GWR;

   Abstract : The objective of this study is to develop a multiple linear regression model that measures the relationship between the church services supply and the attendance to the services in the Uppsala diocese, Church of Sweden. By reviewing previous models and examining the nature of data available, two research questions were introduced, namely, the problem of omitted variables and the problem of spatial autocorrelation.

5. 14. Blind source separation in real time using Second Order statistics

   University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

   Author : Lakmal Silva; Zhu Bo; [2007]
   Keywords : Blind source separation; convolutive mixtures; second order statistics; Adaptive decorrelation; Real time processing;

   Abstract : A multi stage approach to speech enhancement methods improves the quality of separation over standard techniques such as spectral subtraction and beamforming. Two algorithms are implemented for convolutive mixtures in two of the important stages of a speech enhancement system, the source separation stage and the background denoising stage. READ MORE
