说明：  用matlab编写的升余弦成形滤波器的产生及画图(Generation and drawing of raised cosine shaping filter)

一个波束形成的例子，比较了在瑞利信道中使用波束成形和不使用波束成形的误码率。(An example of beamforming is made to compare beamforming and without beamforming bit error rate in Rayleigh channel.)

DRM(Digital Radio Mondiale)系统采用OFDM调制方式， 引入了先进的信源信道编码和调制技术，使得AM波段的音频广播质量大大提高，在保持现有10kHz带宽时接近了FM广播的质量[5](DRM (Digital Radio Mondiale) system uses OFDM modulation, the introduction of advanced source-channel coding and modulation techniques, making AM-band audio broadcast quality greatly improved, while maintaining the existing 10kHz bandwidth close to the quality of FM broadcasting [5])

说明：  设计一个数字低通滤波器，来近似一个理想数字滤波器(Design a digital low-pass filter to approximate an ideal digital filter)

用C#实现的modbus协议源码，非常有价值(modbus protocol by csharp)
