对含储能和风电的电力系统进行了可靠性评估，利用序贯蒙特卡洛法，把风储系统接入IEEE-RBTS系统来仿真，探讨了风电场、储能系统、储能容量和储能最大充放电功率对系统可靠性的具体影响。(The reliability of the power system with energy storage and wind power is uated. The wind storage system is connected to the IEEE-RBTS system by using the sequential Monte Carlo method. The wind farm, energy storage system, storage capacity and storage capacity are discussed. The maximum impact of the maximum charge and discharge power on the system reliability.)

多址干扰一直是造成cdma系统容量限制的重要原因，本程序主要模拟了多址干扰对每个用户的影响以及把多址干扰作为高斯白噪声看待时对用户的影响(MAI has been caused CDMA system capacity limit of the important reasons the procedures simulated the MAI for each user to the effects of MAI as a Gaussian white noise when users view the impact)

mvdr算法是最小方差无畸变响应波束形成器，它的原理来自是使非期望波达方向的任何干扰贡献的功率最小，但又能保持观测方向的信号功率不变。(mvdr algorithm is the minimum variance beamformer response distortion, its principle is that any interference from the direction of arrival of the undesired contributions to a minimum power, but the power of the signal while maintaining constant observation direction.)
