Description: Kevin Murphy的条件随机场matlab和c++混合代码，包含chains, trees and general graphs includes BP code。-This package is a set of Matlab functions for chain-structured conditional random fields (CRFs) with categorical features. The code implements decoding (with the Viterbi algorithm), inference (with the forwards-backwards algorithm), sampling (with the forwards-filter bacwards-sample algorithm), and parameter estimation (with a limited-memory quasi-Newton algorithm) in these models. Several of the functions have been implemented in C as mex files to speed up calculations. Platform: |

Description: 均衡效果好，这是基于最大似然估计的均衡器-With the development of high-speed optical fiber communication systems, polarization
mode dispersion (PMD) has become a vital limiting factor. However, the traditional
compensation methods which in optical domain have the disadvantages of complexity and cost.
In recent years, the compensation methods which in electronic domain are given more attention
because of their outstanding price advantage and their strong adaptability.
The maximum-likehihood sequence estimation (MLSE) equalizer based on the Viterbi
algorithm was designed in this paper.The MLSE equalizer can effectively compensate the
intersymbol interference caused by polarization mode dispersion (PMD). First, the background
and the spectrum of the text were introduced also the principles of PMD and the FFE/DFE
equalizer were analysed. Second, the principles of Viterbi and the structure of MLSE were
researched also the MLSE equalizer was simulated with the Matlab program in the optical fiber
communication systems. T Platform: |
