16. Weighted Regression with Application to Array Antennas
Sammanfattning : A nonlinear system can be modelled with a simple linear model ifthe model is only valid locally. This can be done by assigningweights to the estimation data, as a function of the distance tothe modelled point. The weighting is here used to develop adirection-dependent calibration method for array antennas. LÄS MER
17. The ubiquitous signal processing : Applications to communications, spectral analysis and array processing
Sammanfattning : This dissertation is concerned with statistical signal processing and its applications. The thesis consists of three parts: I) applications to wireless communications, II) applications to spectral analysis and III) applications to array processing. LÄS MER
18. Sparse Array Architectures for Wireless Communication and Radar Applications
Sammanfattning : This thesis focuses on sparse array architectures for the next generation of wireless communication, known as fifth-generation (5G), and automotive radar direction-of-arrival (DOA) estimation. For both applications, array spatial resolution plays a critical role to better distinguish multiple users/sources. LÄS MER
19. On performance analysis of subspace methods in system identification and sensor array processing
Sammanfattning : This thesis addresses the issue of performance analysis of subspace-based parameter estimation methods in two different applications, namely system identification and sensor array processing. The objective is to study the quality of the estimated models as the amount of data increases, and to suggest improvements and give user guidelines. LÄS MER
