说明：   Matlab file for simulating a cyclic-prefix (CP) orthogonal-frequency-division-multiplexing (OFDM) system with binary phase-shift keying (BPSK) modulation on each subcarrier. CP-OFDM system includes a repetition code and interleaving across subcarriers as well as a Rayleigh-fading channel model with exponentially decaying power profile.

This file compares three different versions of the Kalman filter. The Kalman filter is used for recursive parameter estimation. The Kalman filter can handle noisy measurements. The first implemented filter (fcn_KF) is the Kalman filter with standard update of the covariance matrix P. The covariance matrix reflects the uncertainties of the predictions. To improve the numerical stability Potter developed a square root update (fcn_KF_SRP) of the covariance matrix P. Another version is the square root covariance update via triangularization (fcn_KF_SRT). This file generates a model. Then the three Kalman filters perform an estimation of the model parameter. At the end the results are compared. Sources: Simon, D. (2006): Optimal state estimation Kaminski, P. (1971): Discrete Square Root Filtering: A Survey of Current Techniques Golub, G.
