用窗函数法实现了FIR数字滤波器的仿真，包括五种窗与低通，高通、带通、带阻四种类型的组和，可实现20种滤波器的设计(FIR filter design)

多输入多输出系统的多用户信号盲分离MATLAB程序。(multiple-input multiple-output system of multi-user Blind Signal Separation MATLAB program.)

fundamentals of digital modulations

this program was made using guide, it gives the energy and power of a ingresed signal.

维纳滤波语音增强算法:语音增强算法的维纳滤波器，通过scalart 1996提出的实现。使用一个决策指导的方法跟踪的先验信噪比。请注意，该信号的第一0.25sec用于模型的噪声，即，它是假定的演讲之后，0.25sec开始(Wiener Filter for Noisy Speech Enhancement, implemented as proposed by Scalart 1996. Uses a decision directed method to track the a priori SNR. Note that the first 0.25sec of the signal is used to model the noise, that is, it is assumed that speech starts after that 0.25sec)

PSK系统半解析仿真 matlab符号间干扰ISI与误码率的关系 与Eb/No的对应关系(Correspondence between PSK system semi-analytical simulation matlab inter-symbol interference ISI and BER with Eb/No)

一个相当好用的matlab函数，由美国国家可再生能源实验室科研人员设计，可以计算太阳的直射维度和方位角。只要输入时间、观测地点即可。 (This algorithm is based on numerical approximation of the exact equations. The authors of the original paper state that this algorithm should be precise at+/- 0.0003 degrees. I have compared it to NOAA solar table (http://www.srrb.noaa.gov/highlights/sunrise/azel.html) and to USNO solar table (http://aa.usno.navy.mil/data/docs/AltAz.html) and found very good correspondance (up to the precision of those tables), except for large zenith angle, where the refraction by the atmosphere is significant (difference of about 1 degree). Note that in this code the correction for refraction in the atmosphere as been implemented for a temperature of 10C (283 kelvins) and a pressure of 1010 mbar. See the subfunction un_topocentric_zenith_angle_calculation� for a possible modification to explicitely model the effect of temperature and pressure as describe in Reda & Andreas (2003). )
