浮点数基本运算 浮点数的基本运算主要有四则运算、符号处理、大小比较，以及浮点数分柝等。 包含头文件 "fn.hpp" #include "fn.hpp" 浮点数基本运算 浮点数的基本运算中有加、减、乘、除、取负、绝对值、相等比较等。 加减乘除 加、减、乘、除四个运算极为相似，都是需要两个参数，结果当然也是浮点数了。 例子： // 加 减 乘 除 btil::fn::plus::value // f1+f2 的结果 btil::fn::minus::value // f1-f2 的结果 btil::fn::multiplies::value // f1*f2 的结果 btil::fn::divides::value // f1/f2 的结果 plus::value::f_val // f1+f2 的结果的值 struct one { static const double f_val = 1.0 } // 两个浮点数 struct two { static const double f_val = 2.0 } minus::value::f_val == 0.5 取负 取负运算就是取一个浮点数的负数。-float basic operations of the basic operations are four major operations, symbols, sizes, and float-watchman"s rattle so. The first document contains "fn.hpp"# include "fn.hpp" float float basic operations of the basic operations are, plus or minus, riding, except from negative, in absolute terms, a comparison of the same.

本文对16QAM解调软信息输出(LLR)理论计算方法进行分析，推导 出其简化解调算法。将两者在性能和计算复杂度方面进行了分析比较，并分别在 高斯白噪声信道和瑞利衰落信道环境下进行仿真(In this paper, 16QAM demodulator soft information output (LLR) theoretical calculation method for the analysis derived simplified demodulation algorithm. Both in performance and computational complexity aspects are analyzed and compared, and in white Gaussian noise channel and Rayleigh fading channel simulation environment)
