说明：  qpsk仿真程序，模块，是一个完整的好程序 不可错过阿。(keying simulation program, module, is a complete program is not to be missed A.)

scilab,开源数值计算方针软件。实现不同信噪比条件下的频域变换仿真程序，可完美兼容matlab。(Scilab, open source software for numerical calculation principle. Than the frequency domain transform simulation program under different signal-to-noise to achieve, can be perfectly compatible with matlab.)

利用Matlab软件编程实现DDS（直接数字频率合成技术）。设时钟的频率为固定值f_C，在CLK的作用下，如果按照0000,0001,0010，…，1111的地址顺序读出ROM中的数据，即表1中的幅值编码，其正弦信号频率为f_01；如果每隔一个地址读一次数据（即按0000,0001,0100，…，1110顺序），其输出信号频率为f_02，且f_02将比f_01提高一倍，即f_02=2f_01；其余类推。这样，就可以实现直接数字频率合成器的输出频率的调节。(Matlab software programming DDS (direct digital frequency synthesis). Clock frequency set to a fixed value f_C, under the effect of CLK, according to 0000,, ..., 1111 of the sequence of addresses in the ROM reads the data, i.e., the amplitude of the encoding in Table 1, the frequency of the sinusoidal signal f_01 if every time a read address data (ie 0000,0001,0100, ..., the order of 1110), the output signal frequency is f_02, and f_02 f_01 than doubled, i.e. f_02 = 2f_01 rest on. This allows direct digital frequency synthesizer output frequency regulation.)

四个光孤子的独立波解同时存在于一个方程中。这里是在MATLAB中的编程。(The independence of the four soliton wave solutions exist in a equation. Here is the programming in MATLAB.)

改进RLS算法，能够递推的方式求mm维矩阵的逆，使运算量降低(Improvement of RLS algorithm, recursive manner to seek mm dimension of the inverse matrix to reduce computation)

说明：  利用在box-muller 和在时域上通过低通滤波器的方法产生多普勒频移的瑞利信道(Using the box-muller, and in the time domain through a low pass filter method produces Doppler frequency shift of the Rayleigh channel)
