该程序可准确计算出每年（只局限于1900到2099年）复活节的日期。(The date of Easter Day every year could be exactly caculated.The year can only be between 1900 and 2099.)

说明：  hiperlan协议中mac接入仿真，one proposed way for random RCH number(hiperlan agreement mac access simulation, one proposed way for random number RCH)

建立了强湍流模式下无线光通信模型，并在模型的基础上讨论了SISO与SIMO中的误码率。(Strong turbulence mode optical wireless communication model, and discussed in the model based on the error rate in SISO and SIMO.)

针对多目标测控问题，提出了一种实用的利用基于圆阵的数字波束形成技术来实现目标跟踪的系统。在系统实际工作于噪声和干扰环境中时，为避免计算梯度时可能出现的数值突变，提出了一种修正的梯度跟踪自适应算法，可靠地实现了权值更新，并对各阵元输出进行加权合并，以获得最大信号输出，同时实现对目标方位角和俯仰角的自动捕获和跟踪，且跟踪迅速、正确、稳定。仿真结果表明了所提出的方案的正确性。(Monitoring and control for multi-objective problem, a practical circular array-based digital beam forming technology to achieve target tracking system. Practical work in the system noise and interference in the environment is investigated in order to avoid calculate the gradient values may be mutations present a modified gradient tracking adaptive algorithms, reliably achieve the right value update, and the output of the array weighted combined to obtain maximum signal output, while achieving the target azimuth and elevation of the automatic capture and tracking, and tracking fast, accurate and stable. Simulation results show that the proposed scheme is correct.)

用时间序列和小波分析相互结合的基于小波的时间序列预测方法，该方法比较可靠，欢迎大家下载。(Wavelet analysis of time series and combined with each other in the time series prediction method based on wavelet, this method is more reliable, welcome to download.)
