Description: 曲线模型的半自适应交互多模型跟踪方法
我存的一篇论文，拿来与大家共享-When using interactive multiple model (IMM) to track targets,to select smallermodel set to better cover the move-
ment property and the maneuvering level of various targets and meanwhile to reduce computation complexity are both worthwhile and
also necessary research tasks to project implementation.The main work is done through the IMM algorithm of curvilinear model,the
construction of angle velocity estimation model and the extension of it to state equations,whichmake it possible for normal acceleration
to be self-adaptively adjusted,hence it reduces the model setto associate onlywithMcurvilinearmodels selatingtotangential acceler-
ation.Computation burden is reduced and algorithm’s applying range is extended.The simulation further proves the conclusion

Description: Paper about a new close loop current model flux observer to estimate the rotor flux, position and velocity of an induction machine. The current observer includes carefully designed sliding mode functions which are derivative of the fluxes along the and axes. Therefore, when the estimated current converges to the measured one, the flux estimation is a mere integration of the sliding mode function. Platform: |

Description: 跟踪问题本质上是一个混合系统的状态估计问题[38】，即利用传感器的离散
观测来估计所感兴趣区域内目标个数和状态的过程，其中目标状态包括运动分量
(位置、速度、加速度)和属性信息(信噪比、谱特征，身份信息等)。目标跟
踪问题根据跟踪环境的不同可以分为单机动目标跟踪和多机动目标跟踪。-Tracking is essentially a hybrid system of the state estimation problem [38】, namely the use of sensors to estimate the discrete observation target region of interest number and status of the process, which includes movement component target state (position, velocity, acceleration) and attribute information (signal to noise ratio, spectral characteristics, status information, etc.). Target tracking problem based on tracking the environment can be divided into single-target tracking, and multi-target tracking. Platform: |

Description: Extended Kalman Filter Tracking Object in 3-D-Assume that we want to track an object moving in 3-D space with constant velocity. Our instruments observe bearing, range and high(cylindrical coordinates). However, of an interest are rectangular coordinates. Since transformation is non-linear this requires use of extended Kalman filter.
Because transformation is non-linear between X,Y and Range,Bearing and linear between Z and high(Z is height), this problems serves as a good comparason of how well extended Kalman filter can perform. By comparing its linear estimation error in Z to non-linear estimations in X and Y, we can judge how non-familiarities effect estimation. Platform: |

Noval统计模型及机动载体的“当前”统计模型-Moving vehicle positioning and navigation general application of the Kalman filter algorithm. Kalman filter algorithm requires a reliable function model, a stochastic model, as well as a reasonable estimation method. Moving carrier in the actual situation is generally difficult to ensure a regular motion, and thus the the precise function model structure is very difficult. In recent years, many scholars have discussed the movement of the motor carrier model, each with distinct characteristics of their respective content, establish various models including the differential polynomial model, constant velocity model, constant acceleration model, time-dependent model, semi-Markov model, Noval statistical model and motor carrier " current" statistical model Platform: |

Description: The function alphaBetaFilter implements a generic algorithm for an alpha-beta filter that is a linear state estimation for position and velocity given an observed data. It acts like a smoothing. Also closely related to Kalman filters and to linear state observers used in control theory. Its principal advantage is that it does not require a detailed system model.

Description: WIMAX_WZ_withencoding:信道估计，相位噪声补偿，频偏估计，编解码都有
WIMAX_WZ_withoutencoding：在上面的工程基础上，去掉编解码部分
WIMAX_WZ_withoutprocessing：在上面的工程基础上，再去掉相位噪声补偿，频偏估计
WIMAX_WZ_withoutprocessing2：在上面的工程基础上，改用新的前导和导频联合信道估计方案,参考文档《基于802_16d标准的OFDM信道估计技术的研究与实现.kdh》
因为白噪声信道仿真只能体现QPSK调制和RS-CC编码的性能，需要仿真SNR可控的SUI信道，来估计信道均衡的性能。
在多普勒频偏fd>100Hz时，联合信道估计性能才比前导估计强，否则前导估计性能更优。对于600MHz中心频率，要求收发机相对运动速度大于180km/h，这种情况出现的概率不大-WIMAX_WZ_withencoding: channel estimation, phase noise compensation, frequency estimation, the codec has WIMAX_WZ_withoutencoding: the project on the basis of the above, remove the codec section WIMAX_WZ_withoutprocessing: the project on the basis of the above, then remove the phase noise compensation, offset estimation WIMAX_WZ_withoutprocessing2: In the project on the basis of the above, use the new leader and pilot joint channel estimation scheme, the document " Standards-based 802_16d OFDM channel estimation and implementation of technology .kdh" because white noise channel simulation only reflects the QPSK modulation and RS-CC coding performance requires simulation SNR controllable SUI channel, to estimate the performance of channel equalization. When Doppler shift fd> 100Hz, joint channel estimation performance was stronger than the leading estimate, otherwise better estimation performance leader.
