PIANO CREATED simple piano in C programming language

1.深入理解最佳基带系统的概念。 2.掌握用Matlab进行通信系统仿真的方法。(digital low-pass filter)

cdma系统matlab仿真程序，信道包括加性白高斯噪声，复合加性白高斯噪声，瑞利衰落，频率选择性瑞利衰落，双信道瑞利衰落。直扩调制，直扩解调。20段小程序，很不错。(cdma system matlab simulation program, channel, including AWGN, complex AWGN, Rayleigh fading, frequency selective Rayleigh fading, dual-channel Rayleigh fading. Direct Sequence Spread Spectrum modulation, demodulation DS. 20 small procedures, is pretty good.)

是关于vblast接收中ML算法的简单的仿真(Receiving on ML algorithm vblast simple simulation)

U盘控制芯片CH331,CH331 是一个小容量U 盘的控制芯片，只要外加一个串行存储器芯片，就可以实现2KB 到512KB 的小容量U 盘。(U disk controller IC CH331, CH331 is a small-capacity USB control chip, As long as plus a serial memory chips, we would achieve 2 KB to 512 KB of small U disk capacity.)

信号与系统matlab实验,各种基础例程，实用(Signals and Systems matlab experiment, a variety of basic routines, practical)

重要参数的提取，小波包分析提取振动信号中的特征频率，一种噪声辅助数据分析方法。( Extract important parameters, Wavelet packet analysis to extract vibration signal characteristic frequency, A noise auxiliary data analysis method.)

rake接收机，简单易懂，来自美国著名教授，如有问题，联系02212090@bjtu.edu.cn()

This is a matlab program that computer the gradient image using 1st derivative of Gaussian
