本程序实现了OFDM系统详尽的方针，注释代码非常丰富，有详细的讲解，可以实现AWGN信道和多径信道，并对最终的如BER等性能指标进行了仿真实现。非常经典。很适用发论文或毕业设计时用来做设计的仿真验证工作。(This procedure detailed implementation of the principle of OFDM systems, notes the code is very rich in detail there is, you can achieve AWGN channel and multi-path channel, and the ultimate properties such as target BER simulation implementation. Very classic. Hair is the application of graduation thesis or design Designed to make the job simulation.)

OFDM-MATLAB
首先根据短训练字的特性进行相关运算，进行信号到达检测，当检测到相关值大于门限一定次数后，认为有信号到达。然后根据长训练字的特性，进行相关运算，进行OFDM符号FFT窗口起始位置的估计。估计出FFT窗口的位置后，先在时域进行小频偏的估计，将两个长训练字进行小频偏补偿后，进行FFT运算，根据FFT运算的结果进行整数倍频偏的估计。这些参数估计完成后，就可以进行数据解调了。先对数据部分进行完整的频偏补偿，然后根据估计的FFT窗口位置进行FFT运算得到频域的数据，进行解调。然后在对应于导频的子载波位置上提取出导频信息，根据导频信息估计出剩余定时误差以及剩余的信道响应误差，将误差量送入环路进行跟踪。当收到所有数据后，重新回到信号到达检测状态，进行下一次信号到达的检测和信号接收。(failed to translate)

海面上一轮船沿直线匀速前行，速度为30公里/小时，船上有一雷达可用来测距、测角，船长关心的是周围目标那些是活动的船，那些是不动的岩石，若是活动的船，请按下面假设，分析有关因素，给出船的运动方向和速度。(ships on the sea along a straight uniform before the trip and a speed of 30 km/hour, On board there is a radar can be used to measure the distance and angle measurement, the captain of concern is around the goal of those activities is the boat. those are immobile rocks, if the ship by the following assumptions, analysis of the relevant factors, the boat is the direction and speed of movement.)
