ofdm仿真
说明: OFDM即正交频分复用技术,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。。每个子信道上的信号带宽小于信道的相关带宽,因此每个子信道上的可以看成平坦性衰落,从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分,信道均衡变得相对容易。(Orthogonal Frequency Division Multiplexing (OFDM) is a kind of multi-carrier modulation. The main idea is to divide the channel into several orthogonal sub-channels, convert high-speed data signals into parallel low-speed sub-data streams, and modulate them to transmit on each sub-channel. The signal bandwidth on each sub-channel is less than the correlation bandwidth of the channel, so it can be seen as flat fading on each sub-channel, which can eliminate inter-symbol interference. Moreover, since the bandwidth of each subchannel is only a small part of the original channel bandwidth, channel equalization becomes relatively easy.)

遗传算法
说明: 使用遗传算法解决了双旅行商,环路最短路径问题。其中在求解资源最优时,还 使用了退火算法对局部最优值求解(The genetic algorithm is used to solve the shortest path problem of double traveling salesman. The annealing algorithm is also used to solve the local optimal value)

AD7745调试
电容层析成像系统适用
电容层析成像 技术根据被测物质各相具有不同的介电常数,当各相组分分布或浓度分布发生变化时,将引起混合流体等价介电常数发生变化,从而使测量电极对间的电容值发生变化,在此基础上,利用相应的图像重建算法重建被测物场的介电分布图。目前电容层析成像分为圆周是和平面式两种。(The application of electrical capacitance tomography system)
