Abstract


TDD CDMA system of Arrival direction ( DOA ) , to reach the joint estimation of the delay and polarization parameters for a more in-depth study . First analysis of several algorithms for the array signal multi-parameter joint estimation and simulation , on this basis , proposed a polarization sensitive array - based TDMA system multipath channel the 2D angle / delay / polarization joint estimation of new method. Furthermore, a multi-user TDD CDMA system based on polarization sensitive array , the multipath channel two-dimensional angle / delay / polarization estimation the new method , the method of the combination of polarization sensitive array antenna and TDD CDMA system up to study the multi-user TDD CDMA systems , the multipath joint parameter estimation problem , the effective realization of the joint estimation of TDD CDMA system is two-dimensional angle / delay / polarization parameters of the high resolution . The text is divided into six chapters : the first chapter , the introduction on the research background and significance , the array signal processing techniques and polarization sensitive array multi - parameter joint estimation of development history , study the current situation and existing problems . The second chapter , the basic knowledge to introduce TDD CDMA system works , the basic concepts of polarization and characterization of basic knowledge of matrix algebra . Chapter , elaborated the geometric principles positioning mobile station DOA , the the array signal Classic one-dimensional , two-dimensional DOA estimation models and methods , and analyzes the joint angle / delay parameter estimation problems , and JADE joint parameter estimation method simulation and analysis . Chapter to study the polarization sensitive array signal multi- parameter joint estimation method , the first analysis of the angle / polarization estimation method , one-dimensional point of view / delay / polarization (JADPE) , , estimation methods and simulation analysis and compare , based on a two-dimensional point of view based on polarization sensitive array TDMA system multipath channel / delay / polarization joint estimation method , and the effectiveness of the method is verified by simulation . Chapter 5 , research TDD CDMA system is multi- user , multi-parameter joint estimation problem multipath , based polarization sensitive array TDD CDMA system two-dimensional angle / delay / polarization joint estimation methods , and through simulation the experimental verification of the validity of the method . Chapter VI , summarizes this paper and gives outlook .
