卡尔曼滤波器进行信道估计的一篇文章，适用于OFDM-MIMO系统。(Kalman filter for channel estimation in an article for OFDM-MIMO systems.)

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.

最优分割的基本思路是给定一个数据序列和分层数，通过搜索所有可能的划分方案，找到段内离差平方和的总和最小的一种方案作为最终划分方案。这里给出最优分割法的Matlab源程序(The basic idea is optimal partition for a given data sequence and hierarchical number divided by searching all possible solutions to find the segment and the sum of the squared deviations smallest division of a scheme as a final solution. This gives the optimal segmentation Matlab source)

Introduction Fiber-to-the-Premises solutions today vary from high-bandwidth, symmetrical and dedicated fiber Ethernet-to-the- Home (ETTH), to traditional TDM PON, such as Gigabit PON (GPON), solutions that are asymmetrical, share bandwidth among users and are not flexible nor scalable to address various residential requirements and enterprises in one infrastructure.
