略谈matlab中S函数的概念及使用_files

公司最近项目做的一个DDC（数字下变频）simulink建模模型 真情奉献给大家(this is a project about digital down-converter,it is bulit with Simulink.)

阈值法实现灰度图像分割，效果不错，可行，可以借鉴(Threshold method to achieve gray-scale image segmentation, the effect of a good, viable, can learn from)

The statements below guide us to write the code for the transmission of sensed data to a sink node using cognitive radios in multiple spectrum bands. In doing this we are trying to find the most appropriate modulation scheme using MATLAB simulation.

We see that HTH matrix is almost diagonal as the off diagonal elements are nearly zero. So we are getting exact estimation in case of PRN INPUT due to diagonality of HTH matrix. As seen that the unknown inpulse response ( h ) and estimated impulse response ( hth ) are coming out to be exactly same. The estimation even gets better for large N .as we get the HTH matrix perfect diagonal. So we come to know that we can estimate the unknown parameters exactly when PRN input is used.
