说明：  利用共軛梯度法求解線性聯立方程組 從整體來搜索最佳方向(Using conjugate gradient method for solving linear simultaneous equations to search for the best direction for the overall)

基于四阶累积量的联合对角化，其中给出两种四阶累积量计算方法，方便理解。这个算法还是比较难的，可以参看下独立分量分析中的jade算法(Fourth-order cumulant-based joint diagonalization, which gives two fourth-order cumulant method, easy to understand. This algorithm is quite difficult, you can see under the jade independent component analysis algorithm)

CA models simulation

介绍了matlab的各种学科工具箱，如信号处理工具箱，神经网络工具箱等(Introduced a variety of disciplines matlab toolbox, such as the Signal Processing Toolbox, Neural network toolbox, etc.)

自适应信号处理，最终的权值矩阵就是滤波器的系数，学习曲线描述其收敛特性(Adaptive signal processing, the final weight matrix is the filter coefficient, the learning curve to describe the convergence properties)

说明：  认知无线电里的能量检测，适合初学者，比较简单(Energy detection in cognitive radio, suitable for beginners, is relatively simple)

The is a fully functional GPS SDR. It can accept real data or simulate its own data. It performs correlation, signal parameters discrimination, and loop filtering both code and carrier with the option of carrier loop aiding of the code loop. There are many support functions such as the numerically controlled oscillator, coarse acquisition code generator that are in the archive. This does not include the acquisition engine, just the channel tracking state machine. The also outputs carrier phase measurements and modulo 1ms pseudorange.

用matlab编写的一个地球图片程序，很有意思。(Using matlab to prepare a global picture of the process, a very interesting question.)
