i am uploade matlab code for perfomance analysis of OFDM systyem using different modulation scheme.it simulatoion result is so interesting to propose the modulation scheme when OFDM system is use in application .

利用双线性变换法，设计一个0.4dB截止频率为10kHz且在30kHz处有最小阻带衰减为50dB的数字巴特沃兹低通滤波器，其抽样率为100kHz。利用教材（4.35）式求解原型模拟滤波器的阶数，并利用Matlab的M文件buttap设计模拟原型滤波器。用M文件bilinear将模拟滤波器传输函数变换成期望的数字传输函数。请用Matlab画出其增益和相位响应，并给出设计的具体步骤。(fuck!!!)
