　OFDM —— OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术，实际上OFDM是MCM Multi-CarrierModulation，多载波调制的一种。其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。此程序为ofdm仿真程序！(OFDM- OFDM (Orthogonal Frequency Division Multiplexing) that is orthogonal frequency division multiplexing, OFDM is the fact MCM Multi-CarrierModulation, a multi-carrier modulation. The main idea is: The channel is divided into a number of orthogonal sub-channel, high-speed data signals into parallel low-speed sub-data stream, modulated to be transmitted in each sub-channel. This program is ofdm simulation program!)

使用matlab编程，图论最短路线的Ford迭代算法、Dijkstra算法和Floyd算法(Ford shortest graph theory iterative algorithm)

说明：  用matlab编的语音增强的一个程序，是用维纳滤波实现的，(Matlab made use of a speech enhancement procedure, Wiener filter is used to achieve,)

这是一篇很好的有关信道估计的文章， 可以用来快速的了解信道估计的基本内容(and MAI induced by multiple-input, multiple-output channels. In particular, this article reviews the typical inverse filter criteria (IFC) based algorithm, super-exponential algorithm, and constant modulus algorithm along with their relations, performance, and improvements. Several advanced applications of these algorithms are illustrated, including blind channel estimation, simultaneous estimation of multiple time delays, signal-tonoise ratio (SNR) boost by blind maximum ratio combining, blind beamforming for source separation in multipath, and multiuser detection for direct sequence/code division multiple access (DS/CDMA) systems in multipath.)

对均衡进行初始化，并计算固定均衡矩阵等固定参数。 (Initialization and calculation of ixed parameters, e.g. cell positions,equalization matrix etc.)

this file describes and run the FILTERING of a picture.

说明：  利用matlab软件和时域有限差分方法来算三维结构的程序，采用了周期边界条件(Using matlab software and finite difference time domain method to count three-dimensional structure of the program, using the periodic boundary condition)

宽带信号的DOA估计算法，可以实现宽带信号的doa估计(doa estimation algorithm for wide signal )

主要是对lorenz系统进行仿真，包括时间序列分析，lyapunov指数的分析等等(Is the lorenz system simulation, including time series analysis, analysis of lyapunov index)

有关FM调制的实例，很有针对性，运行通过(FM modulation for instance, very targeted, run by)
