PID_Demo_for_MATLAB7

实现射频中2*1，3*1,4*1空时分组码误码性能分析(Error performance analysis of 2*1, 3*1,4*1, and in RF)

this is bp-recurrent code,hope be useful

可以对信号进行三点五次滤波，减少外在环境对数据造成的干扰(Three points five times the signal can be filtered to reduce the interference caused by the external environment on the data)

说明：  利用SVD进行信号降噪，通过fft判断奇异值个数，确定重构矩阵结构(Using SVD to reduce the noise of signal, using FFT to determine the number of singular values, and determining the structure of reconstruction matrix)

RLS算法,编写了MATLAB程序实现自适应干扰对消.给出信号实例,用于验证所编写程序的性能(RLS algorithm, written MATLAB program to achieve adaptive interference cancellation. Given the signal instance, used to validate the performance of the programming)

matlab中分别用牛顿法，二分法及迭代法求解方程的程序，及其比较(matlab scripts for solving eq. by the means of newton ,bisection and iteration)

The demo shows two nonlinear interference cancellation methods - Zero-Forcing and Minimum-Mean-Square-Error - with symbol cancellation and compares their performance with the Maximum-Likelihood optimum receiver.

rectifier model which converts AC to DC matlab based

说明：  用matlab编写的程序，实现区域的分裂和合并，并带有图像(Matlab prepared using the procedures of the division and regional merger with images)

通过学习BP神经网络技术，对手写数字进行识别，基于结构的识别法及模板匹配法来提高识别率。(Through the study of BP neural network technology, digital handwriting identification, structure-based identification method and template matching method to improve the recognition rate.)
