Transmitter position estimation methods demonstrated on a GPS-SDMA-system

Different methods to estimate the position of transmitters in a SDMA system are presented. To achieve the required position detection accuracy in a SDMA system the parameter estimation of the transmitter positions is performed by classical methods (based on the Fourier transform) as well as parametrical high-resolution methods (eigenanalysis-based methods and autoregressive methods). The position detection accuracy of these methods is compared using a two-transmitter constellation for a GPS satellite tracking system with a smart antenna     «
