multi_booth
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.)

rayleighnew
瑞利衰落信道，是一种无线电信号传播环境的统计模型。这种模型假设信号通过无线信道之后，其信号幅度是随机的，即“衰落”，并且其包络服从瑞利分布。这一信道模型能够描述由电离层和对流层反射的短波信道，以及建筑物密集的城市环境。(Rayleigh fading channels, the statistical model of a radio signal propagation environment. This model assumes that after the signal through the radio channel, the signal amplitude is random, ie, the " fading" and the envelope of the Rayleigh distribution. This channel model is able to describe the HF channel reflected by the ionosphere and troposphere, as well as building a dense urban environment.)
