channel_estimation

this code is used to solve bueden method

这个是matlab中的二次型时频表示的全部代码。(this is the Matlab quadratic time-frequency representation of all the code.)

The architecture of this set of codes and the interaction among them is shown in Figure 1. The main testing code main code.m calls the code riemann grad unit opt.m that performs Riemannian optimization under unitary matrix constraint. Steepest Descent/Ascent (SD/SA) algorithm (see Table 3.2 in [1]), Conjugate Gradient (CG-PR, CG-FR) algo- rithms (both Fletcher-Reeves and Polak-Ribi`ere formulas, see Table 3.3 in [1]), are im- plemented. This code further calls the codes implementing line search methods: Armijo method geod search armijo.m, as well as the polynomial and DFT-based approximation

信号频谱绘制函数，绘制输入输出函数，并计算信号的sndr。(Signal spectrum drawing functions to draw input and output functions, and calculate sndr signal.)

说明：  这个仿真程序可以仿真牛头刨床的运动形式，解牛头刨床的运动加速度等。(This simulation program can simulate the form of the movement of the planer, the solution of the movement of the planer acceleration.)

卡尔曼滤波不错的程序，很实用，大家好好研究一起分享一起进步吧(Kalman filtering good program, very practical, we make good progress in research to share with the Bar)
