在matlab上的FDTD程序关于一维时域有限差分(Matlab program on the one-dimensional FDTD finite difference time domain)

:元胞自动机不仅是理论计算机科学领域的一个重要的计算模型,而且可视为一无限维的离散动力系统,被广泛应用于 自然科学和社会科学各领域的复杂性的研究中,是一个重要的研究方法和工具。该文以Matlab 为开发工具,开发了元胞自 动机的可视模型,为其在各个领域的复杂性研究提供了一个简易、可行的计算机仿真工具(MATLAB s version of Conway s Game of Life. "Life" is a cellular automaton invented by John Conway that involves live and dead cells in a rectangular, two-dimensional universe. In MATLAB, the universe is a sparse matrix that is initially all zero. Whether cells stay alive, die, or nerate new cells depends upon how many of their eight possible neighbors are alive. By using sparse matrices, the calculations required become astonishingly simple. We use periodic (torus) boundary conditions at the edges of the universe. Pressing the "Start" button automatically seeds this universe with several small random communities. Some will succeed and some will fail. )

注水算法是根据某种准则，并根据信道状况对发送功率进行自适应分配，通常是信道状况好的时刻，多分配功率，信道差的时候，少分配功率，从而最大化传输速率。本文运用matlab通过对注水算法在mino系统中的三种不同的情况下进行了仿真，比较出在小信噪比时，相同信噪比下利用CSI的功率注水算法获得容量优于未知CSI的平均功率分配算法；相同容量下已知CSI信噪比比未知CSI时的信噪比小3dB.当信噪比增大到一定程度时，功率注水算法所获得的信道容量将收敛到平均功率分配的信道容量。(Water flooding algorithm is based on certain standards, and according to the channel condition to adaptive allocation of sending power, usually is a good moment, channel situation more distribution power, channel is poor, less power distribution, so as to maximize the transmission rate. This paper USES matlab based on water flooding algorithm in Austin system of three different cases are simulated and compared in small SNR, under the same SNR use CSI power allocation algorithm for capacity is superior to the average power allocation algorithm of unknown CSI Same capacity known CSI signal-to-noise ratio than the unknown CSI small signal-to-noise ratio of 3 db. When the signal-to-noise ratio increases to a certain degree, the power allocation algorithm for channel capacity will converge to the average power distribution channel capacity. )
