单自由度系统对初始条件和简谐激励相应 由单自由度的运动方程和初始条件得到二阶非齐次常微分方程，它的解有对应的齐次方程的通解和非齐次方程的特接构成。(Single degree of freedom system to initial conditions and the corresponding harmonic excitation Special general solution of the equations of motion and initial conditions by a single degree of freedom to get the second order non-homogeneous ordinary differential equations, its solution has a corresponding homogeneous equation and non-homogeneous equation then constituted.)

从simulink仿真可以看到瑞利衰落信道对于bpsk性能的影响。(Simulink simulation can be seen from the Rayleigh fading channel performance for bpsk.)

CDMA业务信道卷积编码实现，根据上下行信道区分生成不同码率的卷积码序列，original_sequence是原始输入序列，channel_select是信道选择参数，其中下行码率为1/2，上行信道为1/3 (CDMA business channel convolutional coding to achieve, according to the distinction between upper and lower line to generate a different channel bit rate of the convolutional code sequence, original_sequence is the original input sequence, channel_select is channel selection parameters, which downlink bit rate of 1/2, upstream channel for the 1/3)
