说明：  通过MONTE CARLO仿真说明DS扩频信号在抑制正弦干扰方面的有效性(MONTE CARLO simulation shows through the DS spread spectrum signal is sinusoidal interference suppression in the effectiveness of)

matlab的 通信 系统仿真，希望对大家又帮助(Matlab communications system simulation, we also hope to help)

核查的关键在于对核材料属性准确、有效地识别[1][2]。利用252Cf作为随机脉冲中子源，对其入射核材料所产生的诱发裂变中子脉冲信号进行采集、处理和分析，得到自相关、互相关、自/互功率谱、功率谱密度比等一系列参数，从而反演核材料内部的反应性的情况，便可用于分析和识别核材料，其基本原理就是252Cf中子源驱动噪声分析测量法[(The result shows that the trained Elman neural network is able to identify the characteristics of correlation function, to distinguish different concentrations, and the average recognition rate reaches 90 , with high robustness.)

引力搜索算法与粒子群算法结合的混合算法，多大量的标准测试函数进行测试(Hybrid algorithm gravitational search algorithm and particle swarm algorithm combining multiple large number of standard test functions for testing)

该程序很详细的比较分析了协作通信三个节点时系统在直接转发、存储转发AF和DF模式下的理论与仿真误码率曲线。(The program is very detailed comparative analysis of the collaborative communication system in direct forward three nodes, store-and-forward AF and DF mode theory and simulation of the ber curve.)

说明：  使用一条折线、一组多点标记和位图字符标号来生成一年内按月的折线图。(Using a polyline, a group of multi-point markers and labels to generate bitmap character within one year of the monthly line chart.)

程序代码说明 P0610：神经网络的实例(Procedure Code Description P0610: examples of neural network)

Source code for MD5 in matlab

uses the message signal X to modulate the carrier frequency Fc (Hz) and sample frequency Fs (Hz), where Fs > 2*Fc. FREQDEV (Hz) is the frequency deviation of the modulated signal.

说明：  通过迭代的方法来计算物质的光学性质，通过最小二乘法来设置收敛的条件，当结果小于收敛条件时，输出结果(Calculate liquid refractive index, using the iteration method, design the smallest error by the least squares method, to terminate the iteration convergence )
