混合扩频DS/FH仿真程序，从原始信号通过伪随机码，跳频码转变为混合扩频信号，再依次解跳解扩，最后通过低通滤波器恢复出信号。-Hybrid spread spectrum DS/FH simulation program, from the original signal by pseudo random code, frequency hopping code into a hybrid spread spectrum signal, and then hopping despreading,

虚拟低通滤波器设计：可以产生正弦信号和白噪声时域信号波形，以及混杂噪声的正弦波波形，信噪比可调。-Virtual low-pass filter design: sinusoidal signal can be generated and the time-domain white noise signal waveform, and hybrid noise sine wave signal to noise ratio is adjustable.
