数字通信中,信号的频移键控的4FSK调制仿真,采用四种不同的频率调制二进制二进制比特流。(Digital communication 4FSK modulation simulation)

OFDM 系统信噪比估计，matlab源代码(OFDM system, SNR estimation, matlab source code)

离散二次线性系统最优控制问题的MAtlab 原程序代码(Discrete linear systems with quadratic optimal control problem of the original Matlab code)

说明：  MATLAB以矩阵作为数据操作的基本单位，还提供了十分丰富的数值计算函数。MATLAB和著名的符号计算语言Maple相结合，使得MATLAB具有符号计算功能。(MATLAB with matrix as the basic unit of data manipulation, it also provides a very rich numerical functions. MATLAB and the famous combination of symbolic computation language Maple, MATLAB has a symbolic computing makes.)

这是我先根据MATLAB设计的一个FIR滤波器，然后c语言实现，是二阶的，非常好用。(This is my first one under the MATLAB FIR filter design, and then c languages to achieve, is the second order, quite well.)
