Mean Shift 這個概念最早是由Fukunaga等人[1]于1975年在一篇關于概率密度梯度函數的估計中提出來的,其最初含義正如其名,就是偏移的均值向量,在這里Mean Shift是一個名詞,它指代的是一個向量,但隨著Mean Shift理論的發(fā)展,Mean Shift的含義也發(fā)生了變化,如果我們說Mean Shift算法,一般是指一個迭代的步驟,即先算出當前點的偏移均值,移動該點到其偏移均值,然后以此為新的起始點,繼續(xù)移動,直到滿足一定的條件結束. 用matlab實現mean shift算法仿真

observable distribution grid are investigated. A distribution grid is observable if the state of the grid can be fully determined. For the simulations, the modified 34-bus IEEE test feeder is used. The measurements needed for the state estimation are generated by the ladder iterative technique. Two methods for the state estimation are analyzed: Weighted Least Squares and Extended Kalman Filter. Both estimators try to find the most probable state based on the available measurements. The result is that the Kalman filter mostly needs less iterations and calculation time. The disadvantage of the Kalman filter is that it needs some foreknowlegde about the state.

In this project we analyze and design the minimum mean-square error (MMSE) multiuser receiver for uniformly quantized synchronous code division multiple access (CDMA) signals in additive white Gaussian noise (AWGN) channels.This project is mainly based on the representation of uniform quantizer by gain plus additive noise model. Based on this model, we derive the weight vector and the output signal-to-interference ratio (SIR) of the MMSE receiver. The effects of quantization on the MMSE receiver performance is characterized in a single parameter named 鈥漞quivalent noise variance鈥? The optimal quantizer stepsize which maximizes the MMSE receiver output SNR is also determined.

This is GPS in matlab calculatePseudoranges finds relative pseudoranges for all satellites listed in CHANNELLIST at the specified millisecond of the processed signal. The pseudoranges contain unknown receiver clock offset. It can be found by the least squares position search procedure.
