atan_base_on_CORDIC_arithmetic
- 用CORDIC算法实现的2参数反正切。结果的精度与CORDIC的迭代次数有关,迭代次数越多,精度越高。本例子中精确到小数点后4位。要提高迭代次数,还得把增加1QN格式的位数,比如32位long,程序多处需要修改,有需要的话自己改吧。 -CORDIC algorithm with the two parameters arc tangent. And the accuracy of the CORDIC iteration number, the more the number of iter

cordic_atan
- 用verilog语言实现计算反正切函数,在软件无线电中解调PM/FM中使用的尤为频繁。上传的压缩包是modelsim工程,基于6.5c,里边包含一个完整的PM波产生以及解调过程的matlab文件仿真,并取其中间的I和Q支路做为verilog文件的输入,并将其借条输出与MATLAB实际解调输出作比较。 鉴相器的设计基于CORDIC算法,其精度取决于迭代的深度。由于工程实际运用只需要解调出atan值,并不需要绝对的值,所以并没有给予加权,需要的同学可以自己加上。-Calculated usin

ExpandingRods
- 题意:已知一个圆的弦长l0及这条弦所在的弧长l1,求弦的中心点到弧的中心点的距离 思想:这是一个列方程然后利用二分法解方程的题目,令该疑弧所对的圆心角为anlg, 半径为r,根据题意有两个方程:l1=anlg*r l0=2*r*sin(anlg/2) 两个方程两个未知数, 通过化简有:2*l1*sin(anlg/2)-anlg*l0=0 因为角度的值是从0到2*pi,题目中讲到过 弧的长度不可能大于弦的两倍,所以角度不可能取到2*pi,但是有可能为0,把零特殊考虑, 再从0到
