This is about the speaker recognition system, this system is about automatically recognizes the speaker speech. and this is the present active research filed in speech processing

instrumental variable identification method

matlab/C++ 源代码，在数字相关技术中应用非常高效准确。(matlab/C++ source code in digital image correlation. It s very useful and convenient)

compensation of dead time effect of the inverter dead time effect causes the impact of the control performance of the INVERTER system, and pointed out that the dead time compensation, the key lies in the current phase of the acquisition, in order to overcome the practical zero of the current ambiguity of the system is proposed based on the two-phase stationary coordinate system under the feedforward dead-time compensation method. by the offset voltage of the three-phase output current cycle Fourier transform is found only compensation 1, 5, 7 harmonic components to eliminate the dead time effect. simulation and experimental results verify the correctness and feasibility of this approach.

说明：  newton插值应该比lagrange好一点点，适合求解线性方程组，(lagrange interpolation newton than a little bit of good, suitable for solving linear equations,)

ldpc码在AWGN信道下的性能仿真。包括geth.m,getG.m,H2G.m,decode.m,BER.m按传统的编码方案编码，生成H矩阵后转化为G矩阵，编码后送入高斯信道。仿真得到BER性能(ldpc codes in the AWGN channel performance simulation. Including geth.m, getG.m, H2G.m, decode.m, BER.m coded according to the traditional encoding scheme to generate H matrix is transformed into G matrix encoded into the Gaussian channel. Simulation, the BER performance)
