: 正交频分复用( O F D M) 是第四代移动通信的核心技术。 该文首先简要介绍了O F D M基本原理, 重点研究了理想同步情
况下, 保护时隙( c P )和不同的信道估计方法在高斯信道和多径瑞利衰落信道下对O F D M系统性能的影响。 在给出O F DM系
统模型的基础上, 用 MAT L A B语言实现了整个系统的计算机仿真并给出参考设计程序。 最后给出在不同的信道条件下, 保
护时隙、 信道估计方法对 OF DM系统误码率影响的比较曲线, 得出了较理想的结论。

须尽快逃离洞穴。精灵王子的跑步速度为17m/s,以这样的速度可能是无法逃出洞穴的。庆幸的是精灵王子拥有闪烁法术,可在1s内移动60m,不过每次使用闪烁
法术都会消耗魔法值10点。精灵王子的魔法值恢复的速度为4点/s,只有处在原地休息状态时才能恢复。现在已知精灵王子的魔法初值M,他所在洞穴中的位置与
洞穴出口之间的距离S,距离洞穴塌陷的时间T。你的任务是写一个程序帮助精灵王子计算如何在最短的时间内逃离洞穴。(In the depths of the cave, the elven prince accidentally touched a hidden cave organ, the entire cave will soon collapse, elf prince will

fem1d_spectral_numeric
FEM1D_SPECTRAL_NUMERIC is a MATLAB program which applies the spectral finite element method to solve the problem u = - pi^2 sin(x) over [-1,+1] with zero boundary conditions, using as basis elements the functions x^n*(x-1)*(x+1), and carrying out the integration numerically using MATLAB s quad() function. This function solves the problem u = - pi^2 * sin( pi * x ) for x in (-1,1), with boundary conditions u(-1) = u(1) = 0.
