viterbi算法的matlab实现，主要用于数字通信中接收端的译码(viterbi)

光通信中3*3耦合器相位解调的仿真，包括对称解调与非对称解调两种。(Optical Communication 3* 3 coupler phase demodulation of the simulation, including demodulation and demodulation of two symmetric asymmetric.)

说明：  对信号的边际谱分析,三维能量谱分析以及时频分析的有关程序.......(Spectral analysis of the marginal signal, three-dimensional power spectrum analysis and time-frequency analysis of the procedure .......)

支持向量机在波束形成中的一种应用 能够形成波束,且效果很好.(SVM in the beamforming application to form a beam, and the results very good.)

说明：  基于lms算法的干扰自适应抵消LMS算法是基于最陡下降法的统计估计的最小均方值算法，令误差的均方值达到最小时的抽头系数的值即为最优解。LMS算法抽头系数w的变化方向为代价方程的负梯度方向。(Lms algorithm based on adaptive interference cancellation algorithm is the LMS steepest descent method based on statistical estimation of the least mean square algorithm, so that the mean square error to achieve the most hours of the tap coefficient value is the optimal solution. LMS algorithm for tap coefficient w, the cost equation changes in the direction of the negative gradient direction.)
