Description: M-file for simulating a QPSK transmitter by modulating with a pseudo random bit stream. A serial to parallel conversion of the pseudo random bit stream is performed with mapping of two bits per symbol. A cosine and sine carrier is configured and the I and Q symbols modulate these carriers. The I and Q carriers are combined and time and frequency domain plots are provided showing key waveforms at various positions in the QPSK transmitter.

Description: 图论中最小生成树Kruskal算法 及画图程序 M-函数
格式 [Wt,Pp]=mintreek(n,W):n为图顶点数,W为图的带权邻接矩阵,不构成边的两顶点之间的权用inf表示。显示最小生成树的边及顶点, Wt为最小生成树的权,Pp(:,1:2)为最小生成树边的两顶点,Pp(:,3)为最小生成树的边权,Pp(:,4)为最小生成树边的序号 附图,红色连线为最小生成树的图
例如
n=6 w=inf*ones(6)
w(1,[2,3,4])=[6,1,5] w(2,[3,5])=[5,3]
w(3,[4,5,6])=[5,6,4] w(4,6)=2 w(5,6)=6

Description: ST7529液晶驱动 The ST7529 is a driver & controller LSI for 32 gray scale graphic dot-matrix liquid crystal display systems. It generates 255
Segment and 160 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral
Interface (SPI), 8-bit/16-bit parallel or IIC display data and stores in an on-chip display data RAM. It performs display data
RAM read/write operation with no external operating clock to minimize power consumption. In addition, because it contains
power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.-ST7529 LCD driver The ST7529 is a driver Platform: |

Description: 解决TSP问题的TS算法MATLAB实现,其中加入了变异算法,当然也可以去掉这个步骤,调用TS_TSP(N, inStart, IsBianYi),N是城市数目,inStart是起始城市的序号,IsBianYi就是选择变异否,如果为0则不要变异,否则就是结合变异算子的TS算法。
至于下面的参数可以自己调:
T:总的循环次数;
tabulength:禁忌长度;
Pby:变异概率;
-Solve the TSP problem MATLAB realize TS algorithm, which joined the variance algorithm, of course, this step can also be removed, call TS_TSP (N, inStart, IsBianYi), N is the number of cities, inStart is the serial number of the starting cities, IsBianYi is to choose variation has, if not for the variation of 0, otherwise, it is combined with mutation of the TS algorithm. As for the following parameters can be their own tune: T: total number of the cycle tabulength: taboo length Pby: mutation probability Platform: |
