数字信号的传输：1、实现滚降系数分别为0，0.5，1时信号时域频域和功率谱密度以及眼图的波形，并比较异同。 2、对(2/4/8)PSK,DPSK通信系统进行蒙特卡罗仿真，通过功率谱密度、误比特率来比较他们的性能(采用最佳接收方式)。 (Digital signal transmission: 1, to achieve roll-off coefficients were 0,0.5,1 time domain when the signal frequency and power spectral density, as well as eye-diagram of the waveform, and compare the similarities and differences. 2, (2/4/8) PSK, DPSK communication system, Monte Carlo simulation, through the power spectral density, bit error rate to compare their performance (to adopt the best way to receive).)

C语言编写的直方图求法matlab程序，带详细解释和所需图片(histogram with C language )

本程序是运用matlab模拟嫦娥一号围绕地球运动的代码，它很好很形象的让人们了解了它的运动轨迹。(The program is the use of matlab simulation Chang E the 1st code revolves around the earth, it is very good image to let people know about its trajectory.)
