本软件围绕工程活动图AOE网的应用这一主题，用图形化的界面实现了AOE网的建立、判断工程可行性、计算工程活动开始时间、确定关键路径和关键活动等功能。 具体功能： 已知假想的工程活动图AOE网，试设计一个算法，要求： （1） 判断工程是否可行 （2） 求出工程中每个活动的最早开始时间e(i)，最迟开始时间l(i)和全工程可以完成的最早时间 （3） 确定工程中关键路径和可使整个活动的工期缩短的关键活动 源码在文件夹“源代码清单”中。程序开发时所用的文件在文件夹“配套文件”中提供。另附说明文档。

用fortran语言编写的程序，这样可以在fortran系统中直接运行，为大家提供点方便。-using FORTRAN language of the procedure so in FORTRAN operating system directly, to provide a convenient point.

线性调频信号(Linear Frequency Modulated,LFM)作为一种典型的非平稳信号而且具有大的时间-频带积,被广泛用于各种信息系统。从电子战和电子干扰的角度看,为解决作用距离和距离分辨率的矛盾以及提高信号的隐蔽性，通常采用LFM信号，对于线性调频信号的检测和参数估计,成为电子战研究的重点matlab计算分数阶傅立叶变换运用分数阶傅里叶变换frft对线性调频信号lfm参数进行估计，结果很准确例程完整，有运行结果。

应用背景Massive multiuser MIMO (MISO): ◮ M ≫ K ≫ 1 (think 100 × 10 or 500 × 50) ◮ coherent, but simple, processing ◮ Potential to dramatically improve rate & reliability ◮ Potential to drastically scale down TX power ◮ Not only theory, at least one known testbed (64× ∼10) 关键技术 Massive MIMO Operation Not enough resources for pilots & CSI feedback, so operate in TDD. ◮ On the uplink, ◮ acquire CSI from uplink pilots and/or blindly from data ◮ detect symbols ◮ M ≫ K ⇒ linear processing (MRC, ZF, MMSE) nearly optimal ◮ On the downlink, ◮ use CSI obtained on the uplink ◮ make necessary adjustments based on reciprocity calibration ◮ apply multiuser MIMO precoding ◮ simple precoders desirable (and very good!): MRT, ZF, MMSE, ... ◮ MRC/MRT operation ◮ intracell interference will appear as

用对分法求非线性方程f(x)=0的实根.基本思想：逐步缩小这个有根的区间，当这个区间长度减小到一定程度是，就取这个区间的中点作为根的近似值-Use of sub-method of nonlinear equation f (x) = 0 the real roots. The basic idea: to gradually narrow the range of this well-established, when the interval length decreases to a certain extent, we take the midpoint of this range as the root approximation
