Description: 信道的频率响应是时变的，设计最佳的固定的解调滤波是不可能的，因此，需要一种能补偿或减少接收信号中ISI的方法，这种ISI补偿方法称为均衡方法。
自适应均衡技术能够用来抵消由于信道带限或时间色散所导致的码间干扰，可以使通信系统更有效地利用信道带宽。
-Channel frequency response is time-varying, the best fixed design demodulation filter is impossible, therefore, need to be able to receive compensation or reduce the signal in the ISI method, the ISI compensation is called a balanced approach. Adaptive equalization techniques can be used to offset the channel band-limited or time dispersion caused by the inter-symbol interference can make communication systems more efficient use of channel bandwidth.

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: |

Description: 粘弹性地震波的衰减不仅与传播时间有关，而且与子波的频率、速度场的分布、射线路经、地下构造展布都有关，因此，仅仅利用反Q滤波对粘弹性的吸收和频散做一维补偿不能完全的恢复地震波长的本来特征。-Viscoelastic seismic wave attenuation is not only associated with the propagation time, and and wavelet frequency distribution of the velocity field, the ray path, subsurface structures spread are related, using only inverse Q filtering viscoelastic absorption and dispersion do The one-dimensional compensation can not completely restore the original features of the seismic wavelength.
