The mathematical model used in this study consists a discrete time linear difference equation. Due to the fact that the measurements are taken every second, time step is taken discrete. Both the process noise and the measurement noise are taken to be Gaussian white noise. Simulations are carried out to compare the performance of both the Extended Kalman filter and the SIR Particle filter for two different sets of data.application/pdfengTelecommunication -- Research -- Mathematical modeElectronic noiseBiotelemetry -- Research -- Mathematical modelsGlobal positioning system (GPS)Kalman filtering -- Mathematical modelsThesis
