无线通信中对多种基本调制方式在三种不同信道下的差错概率仿真(Wireless communication modulation of the plurality of basic channels on three different simulation error probability)

说明：  PSO算法和BP神经网络都是现在非常热门的两个算法，在各自的领域都担当着至关重要的作用，通过MATLAB实现pso优化bp中以发挥其最大优势(PSO algorithm and BP neural network are two very popular algorithms, which play an important role in their respective fields. Through MATLAB, PSO optimizes BP to give full play to its greatest advantage)

说明：  结构可靠性分析中的重要度抽样、蒙特卡洛仿真方法(importance sampling technique and Monte Carlo simulation in system structural reliability analysis)

这是本论文的仿真部分，是对MIMO系统理论的验证。本论文将分别从两种情况来对系统进行仿真：不同的信噪比下，发射天线数 为4，接收天线 逐渐增大；不同的信噪比下，接收天线 为4，发射天线数 逐渐增大。然后分别绘出他们的仿真图，并对它进行分析(This is the simulation part of this paper is to verify the theory of MIMO systems. In this paper, two cases will come from the system simulation: different signal to noise ratio, the number of transmission antennas is 4, the receiving antenna is gradually increasing different signal to noise ratio, the receiving antenna 4, gradually increasing the number of transmission antennas Great. And then mapped to their respective simulation map, and analyze it)

matlab通信仿真， 信道编码，好东西(communication matlab simulation, channel coding, good things)

功能：CDMA调变 multiple access b/w 2 users using DS CDMA(multiple access b/w 2 users using DS CDMA format is : cdmamodem(user1,user2,snr_in_dbs) user1 and user2 are vectors and they should be of equal length)
