PSD_estimators

说明：  可以根据用户需要设计任意的模拟滤波器。只需填入截止频率、通频带等参数，该软件就可自动生成滤波器的电路图，以及各个元件的参数。(this software is very useful for designing filter ,you need only input the data ,then it can generate the circuit.)

说明：  To completely remove inter-cell interference, SIC is applied by the receivers at the user side. The technology can separate these data streams for corresponding users The interference cancellation technology is of importance for hybrid unicast/multicast service system performance

正交频分复用中当调制方式采用QDPSK时的解调程序(Orthogonal frequency division multiplexing modulation when used in QDPSK procedures at the time of demodulation)

calculate catalan number

空域零陷，首先用doa技术估计直达波方向，然后置零，用于直达波消除。(In spatial nulling, DOA technique is used to estimate the direction of direct wave, and then zeroing is used to eliminate direct wave.)

GFSK调制通信系统误码率统计，非常有借鉴价值(GFSK modulation communication system bit error rate statistics, the very reference value)

基于BPSK的通信系统程序，上采样，平方根升余弦滤波器(Bpsk - based communication system program)

说明：  维纳滤波 自适应滤波 随机生成模拟信号与数字信号，加入高斯白噪声之后进行滤波(Implementation of Wiener filter and adaptive filter)

该程序可以实现多个客户端互相通讯，如同聊天室(Multiple clients can communicate with each other, just like chat rooms)

多输入多输出系统不同收发天线对系统性能的影响(Multiple-input multiple-output system transceiver antenna different impact on system performance)
