OFDM is one of the best physical-layer candidates for cognitive radio (CR) systems, but rectangular pulse shaping gives rise to large spectrum sidelobes and interferes with the licensed user on the adjacent band. In this paper, an approach is derived based on the signal continuity to measure the spectral decay rate of the shaping pulse for OFDM.

以前写的数值分析里的追赶法的代码,我自己看着是可用的(Previous numerical analysis method to write the code in the catch)

实现语音信号通过低通滤波器后，得到频谱，并且输出滤波前后的图形。(Voice signal through a low pass filter to obtain a frequency spectrum, and outputs the graphic before and after filtering.)

These are som documents about the Civil works. For more information, pls. contact me.

fp=0.2KHz,Rp=1dB, fs=0.3KHz,As=25dB,T=1ms；用脉冲响应不变法设计一Butterworth数字低通滤波器，观察所设计数字滤波器的幅频特性曲线，记录带宽和衰减量，检查是否满足要求。(fp=0.2KHz,Rp=1dB, fs=0.3KHz,As=25dB,T=1ms；The same method to design a digital low-pass Butterworth filter, observe the design of digital filter frequency characteristic curve, recording the amount of bandwidth and attenuation, check with the impulse response meets the requirements.)

这是我在网上找的支持向量机的代码，应该比较普通(support vector machine )

功能列表= mmwrite（文件名，选择... ...） mmwrite是能写的AVI，WMV，的WMA，ASF文件。对于AVI文件，您可以选择从现有的编解码器压缩的音频和视频流。 对于WMV，WMA和ASF的编码默认为16位的Windows Media 9率为44100Hz立体声为98％质量的音频和Windows媒体视频9 98 质量。质量可以指定音频和视频。 环绕声，似乎只与AVI和多通道编码不支持。编写任何其他文件类型不支持。本使用Windows的DirectX基础设施，以便其他操作系统是出于运气。 输入：     文件名：这一定是第一个参数，并指定文件名写。     影片结构：视频结构相匹配的mmread输出。在最低限度，必须有4个领域的“框架”，“时代”，“高度”和“宽度”。该“框架”字段必须是一个结构与一个字段数组“的CDATA”的原始框架，它包含由彩色编码的数据宽度高度（3）UINT8s。钍(function list = mmwrite(filename,...options...) mmwrite is able to write AVI,WMV,WMA,ASF files. For AVI files you can choose from the available codecs to compress the audio and video streams. For WMV,WMA and ASF the encoding defaults to Windows Media 9 44100Hz 16bit stereo 98 quality for the audio and Windows Media 9 Video with 98 quality. The quality can be specified for both audio and video. Surround sound only seems to work with AVI and multi-pass encoding is not supported. Writing any other file type is not supported. This uses Windows DirectX infrastructure, so other OSs are out of luck. INPUT: filename: This must be the first parameter and specifies the filename to write. video structure: The video structure matches the output of mmread. At a minimum it must have 4 fields "frames", "times", "height" and "width". The "frames" field must be a struct array with a field "cdata" that contains the raw frame data encoded as height by width by color(3) as UINT8s. Th)
