cdma系统matlab仿真，在两个用户的背景下采用了直接扩频码实现扩频解扩，bpsk调制解调，程序已经运行过，没有问题！(cdma system matlab simulation, in the context of two users using a direct spread spectrum spreading codes realize despreading, bpsk modem, the program has been run before, no problem!)

Locally linear embedding(LLE)是一个经典的流形学习降维方法，通过LLE发现高维数据潜在的内在维数，可以简化计算、方便可视化处理等。(Locally linear embedding (LLE) is a classic manifold learning dimensionality reduction method, discovered by LLE potential inherent high dimensional data dimension, the calculation can be simplified to facilitate visual processing.)

分析雷达信号方向基于四阶累积量的MUSIC算法可以实现阵列扩展,提高了DOA估计精度、分辨率,降低阵列信号处理对信噪比的要求。(Analysis of radar signal direction of MUSIC algorithm based on fourth-order cumulants can realize array extension, improve the DOA estimation precision, resolution, reduce the requirement of array signal processing of signal to noise ratio.)

说明：  利用Matlab及Simulink建立仿真系统，对PCM量化信噪比进行仿真测试，要求对输入的正弦波进行采样、量化和PCM编码，计算并画出量化信噪比曲线，比较量化信噪比理论值与实际值。(Using MATLAB and Simulink to set up simulation system to simulate and test the quantized signal-to-noise ratio of PCM, it is required to sample, quantize and PCM code the input sine wave, calculate and draw the quantized signal-to-noise ratio curve, and compare the theoretical value and the actual value of the quantized signal-to-noise ratio.)

This interactive game allows you to manipulate and view the rubik s cube in 3D with the click of your mouse. If you get stuck, just click to watch the cube solve itself. Or, just "rearrange the stickers" and start over.(This interactive game allows you to manipulate and view the rubik s cube in 3D with the click of your mouse.

used to remove the blur affecting the images

Inspired with scramble game in android, a algorithm for searching dictionary words based on the traversing of 4x4 word matrix. taking long time to run but a novice idea.

求图像峰值信噪比PSNR的代码matlab版(PSNR PSNR for the image code matlab version)

主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度
