基于Matlab对约瑟夫森结（Josephson Junction）RCSJ模型的交直流I-V特性及非线性混沌现象进行数值模拟。通过计算机数值模拟得到该模型的非线性微分方程数值解，研究了RCSJ模型中各参量对约瑟夫森结的影响，进而简要分析其I-V特性和非线性混沌现象的产生机理，绘制出约瑟夫森结的交直流I-V特性曲线、非线性微分方程的相图及因其高度非线性而引起的通过倍周期分岔和阵发性原理进入混沌状态的分岔图。还给出庞加莱截面及功率谱。(Matlab based on the Josephson junction (Josephson Junction) RCSJ model AC and DC IV characteristics and non-linear numerical simulation of chaotic phenomena. Through computer simulation model by the numerical solution of nonlinear differential equations to study the RCSJ model parameters on the impact of Josephson junction, and a brief analysis of the IV characteristics and the emergence of the phenomenon of non-linear chaotic mechanism, drawn Josephson junction IV characteristic curve of AC-DC, non-linear differential equations and the phase diagram because of its highly nonlinear arising through period-doubling bifurcation and chaotic state of paroxysmal principle of access to the bifurcation diagram. Poincare cross-section and was also given power spectrum.)

环形电流磁感应强度的分布，点电荷等势面的分布、两个点电荷感应强度的分布(The distribution of the potential surface of the ring current distribution of the magnetic induction, the point charge, two point charge distribution of the flux density)

mimo 2x2 qpsk modulation design using simulink,calculate BER

this code is used to determine the parameters of johnson distribution for its bounded distribution .

说明：  Fm 的调制和解调 可以在matlab直接运行，包含模块文件(Fm modulation and demodulation can be run in matlab directly, including the module file)

可以实现QPSK解调的matlab代码，希望对大家有所帮助(realize QPSK mode)
