自编实现快速fft程序，速度较调用系统的fft稍慢(Fast fft own procedures, faster than the system call fft slower)

将偏差的比例、积分、微分通过线性组合构成控制量，对被控对象进行控制(The deviation of the proportional, integral, differential control volume through the linear combination of form, to control the controlled object)

解整数规划问题的matlab程序包 能够很好地解决非线性规划问题(Solving of Integer Programming)

经典的波束赋型代码，有均匀圆形阵列，均匀线性阵列，圆柱阵列，球形阵列等(Classic beamforming code, uniform circular array, uniform linear array, cylindrical array, ball grid array, etc.)

说明：  这是一个AWGN信道下，编译码仿真的C程序。本人已经用它产生数据绘制折线图！包含编码，译码，信道模拟，误码率计算 …… ,程序结构清晰，不复杂，适合与初学者来了解，基本通信流程！(This is an AWGN channel, the decoding simulation C program. I' ve used it to generate data to draw a line chart! Including encoding, decoding, channel simulation, bit error rate ... ..., the program structure clear, not complicated, for with the beginners to understand, the basic communication process!)
