二进制格雷码与自然二进制码的互换 它就是介绍怎么把二进制格雷码与自然二进制码的互换。主要是异或操作(itis to for 2to 2)

说明：  PCI slave IP core, in VHDL language ,has been verified,it is very easy to use. it is an ideal IP to study PCI,design PCI Bridge

说明：  实时声音采集，双通道采集声音信号，并且进行降噪处理和FFT变换(Real time sound acquisition)

the matlab file gives LS, MMSE, LMMSE channel estimation for wireless channel, very short and good

pcm编码 有关线性,A律,mu律的pcm编码的matlab实现(Matlab implementation of pcm coding for pcm coding related to Linear, A-Law and mulaw)

实现BPSK的载波同步，采用的方法是锁频环，最大似然法频率估计(BPSK carrier synchronization is realized,the method is frequency - locked loop and maximum likelihood frequency estimation)

说明：  FM（Frequency Modulation）即调频，习惯上用FM来指一般的调频广播（76-108MHz，在中国为87-108MHz、日本为76-90MHz），事实上FM也是一种调制方式，(FM (frequency modulation) refers to the general FM broadcasting (76-108mhz, 87-108mhz in China and 76-90mhz in Japan). In fact, FM is also a modulation mode,)

基于VC++的一个串口通讯类应用实例,有兴趣的朋友学习一下。(VC++ based on a serial communications application example, friends who are interested to learn about.)

说明：  可以比较两种信道估计算法的BER和均方误差(The BER and mean square error of the two channel estimation algorithms can be compared)

陈式混沌系统的解法，吸引子、时序、功率谱、庞加莱图、分叉图等(The solution of Chen type chaotic system, attractor, timing, power spectrum, Poincare diagram, bifurcation diagram, etc.)
