好好学习下哈 4个偶极子天线阵的辐射场图 学习啊 (learn Kazakhstan under four dipole antenna radiation field of study plans ah)

分析蔡氏电路的相轨迹图,画出了各个变量的三维、二维相图 (Chua' s circuit analysis phase trajectory diagram depicts the various variables dimensional, two-dimensional phase diagram)

一个多重分形谱的计算程序，希望对大家有用(A multi-fractal calculation program, we hope to be useful)

写一个MATLAB程序，实现4个时间同步的CDMA用户的仿真，其中每个用户都使用长度为L=31的不同的Gold序列。每个用户都采用它们代表的Gold序列的二进制（+-1）调制。每个用户的接收端将这个复合的CDMA接收信号相关，而这个复合的信号都在它们各自的序列上受到AWGN的污损（基于按码片相加）。在N=10000信息比特下，仿真估值并画出作为SNR的函数的CDMA通信系统的差错概率。(Write a MATLAB program, the realization of the four time synchronization of the simulation of CDMA users, including the length of each user for use of the L = 31 different Gold sequences. They are used for each user on behalf of the Gold sequence of binary (+-1) modulation. Each user' s receiver will receive the composite CDMA signal, and this composite signal in the sequence of their respective defaced by the AWGN (additive based on the chip by). Information in the N = 10000 bits, the simulation value and draw as a function of SNR of the CDMA communication system the probability of error.)

说明：  修改控制策略扭矩分配模块，离合器改为转速控制(Modify the control strategy torque allocation module and change the clutch to speed control)

fsk 调制解调，有两种解调方法：相干解调和非相干解调(fsk modem, there are two demodulation methods: Coherent demodulation and noncoherent demodulation)

今天上传《数学实验与Matlab》程序，希望对大家有用！(today uploaded "Matlab mathematical and experimental" procedures in the hope that it may be useful right! Thank you!)
