OFDM 自适应算法能够根据信道的状况进行比特和功率的分配，能够有效的降低误码率.本程序综合了迭代注水算法，CHOW算法，FISHER算法，H-H算法，以及自己改进的迭代注水算法程序，并进行了对比，改进的算法在有效性与迭代注水算法基本相近，但复杂度和实际应用性都更强，值得参考。(OFDM adaptive algorithm make the bit and power allocation according to the status of the channel .It can effectively reduce the error rate.This program combines iterative algorithm, water injection CHOW algorithm, FISHER algorithm, the algorithm of H- H,as well as their improved iterative allocation algorithm procedures.And has carried on the contrast, the improved algorithm in effectiveness and iterative allocation algorithm basic similar, but the complexity and practical applications were stronger with worthy of reference.)

ANFISCLUST_10SLOT
working of the fifth generation intelligent radio that is Cognitive Radio (CR) system which works on predictive data rate and propose ANFIS based learning scheme to introduce intelligence in it. The testing data set is taken from training set. Validation data set is unseen data. RMSE and prediction accuracy are used as performance index. Two gaussian membership functions are taken for each input. Error goal was set for .001.Training was for 300 epochs. It is seen prediction accuracy was 91 percentages in testing case and 89 in validation. RMSE difference between validation and testing case very small.

仿真技术在光纤通信实验教学中的应用
通过两个例子，将Optisystem和matlab这两个软件结合进行光学仿真，两个例子分别为光波频率右移和光波幅度调制。通过这两个例子，能很好的理解这两个软件的协同仿真。上传的文件包括文献和源码，还有optisystem的osd文件，文件很全。(Two examples are used to combine the two software Optisystem and MATLAB for optical simulation. The two examples are the right shift of the light frequency and the modulation of the amplitude of the light wave. Through these two examples, we can well understand the collaborative simulation of these two software. Upload files, including documents and source code, as well as the optisystem OSD file, the document is very complete)

程序
说明： 当今世界电子对抗日益激烈，对于雷达低截获和抗干扰能力的研究越来越受到关注。OFDM (Orthorgonal Frequency Division Multiplexing，正交频分复用)雷达具有大时宽带宽积、波形设计方法灵活、频谱利用率较高以及低截获性能好的特性，因此逐渐成为雷达领域的重点研究方向。除此之外，OFDM信号时域和频域波形都比较复杂，当雷达信号采用OFDM技术时，敌方很难精确估计发射信号波形和瞬时频率，使得截获机不容易分析出检测到的雷达信号。当面对敌方的欺骗式干扰时，对于同样具有大时宽带宽积的线性调频信号，OFDM信号具有更好的抗欺骗式干扰的性能，因此OFDM技术在雷达上的运用愈来愈得到关注。(As electronic warfare becomes increasingly fierce, low intercept probability radar has become an important research filed in electronic countermeasures. OFDM (Orthorgonal Frequency Division Multiplexing) radars have gradually emerged due to their high spectrum efficiency, large time-bandwidth product, flexible waveform design methods, and low intercept probability.In addition, because of the complex time-frequency characteristics of the transmitted signal in OFDM radar, the enemy is difficult to estimate the transmitted signal waveform and instantaneous frequency.When faced with enemy deception interference, OFDM signals have better anti-spoofing performance for LFM signals that also have a large time-bandwidth bandwidth product. Therefore, the use of OFDM technology in radar is attracting more and more attention. .)
