关联规则数据挖掘的apriori算法MATLAB程序。。(The apriori association rule data mining algorithm for MATLAB programs. .)

基于quartus的布斯乘法器的verilog 实现。布斯乘法算法是计算机中一种利用数的2的补码形式来计算乘法的算法。该算法由安德鲁·唐纳德·布斯于1950 年发明，当时他在伦敦大学伯克贝克学院做晶体学研究。布斯曾使用过台式计算器，由于用这种计算器来做移位计算比加法快，他发明了该算法来加快计算速度。(The verilog codes of booth multiplier based on quartus. Booth multiplication algorithm is a computer algorithm using the complement form of number 2 to calculate the multiplication. The algorithm was invented in 1950 by Andrew Donald booth, who was working on crystallography at birkbeck college, university of London. Booth used a desktop calculator, and because it was faster to do shifts than to add, he invented the algorithm to speed up the calculations.)

用于生成多用户的单通道的跳频信号的子函数(Frequency Hopping Signal for Generating Multi-user Single Channel)

GBSBEM(几何单反射椭圆模型)可以用来仿真功率－延迟－角度（pda-图）、功率延迟图、时间－角度的联合统计、波达方向的边缘特征和窄带衰落包络。适用于低层系统，包括微小区和微微小区、杂波绕射基站天线、发射机到接收机之间以及发射机和接收机的周围充斥着散射体的情形。由于其适用范围广泛且具有解析性质，揭示了空间无线信道不同特征间的相互联系，是进行研究的理想模型。(GBSBEM (geometric GBSBEM) simulation can be used to power-delay-angle (pda- Chart), power plans delayed, time-point joint statistics, DOA on the brink of decline and narrow envelope. Apply to the lower systems, including Microcell and Microcells, Clutter diffraction base station antenna, between the transmitter and receiver to the transmitter and receiver around the full scattering case. Because of its broad scope of application and analytic nature, Space Channel reveals the different features of the inter-linkages Research is the ideal model.)
